AP’s Spec Corvette: Ferrari Fill-In For Forty Large
After giving the Ferrari Challenge series a shot, AP Miranda decided he’d look for a more welcoming group of drivers in another popular club series. He found Spec Corvette, a cost-conscious series based around the C5, ticked all the boxes at a sixth of the Ferrari’s price.
After a lifetime spent racing karts, Outlaws, and everything in between, AP Miranda decided to take a good chunk of the change he’d made over his career as a professional pilot and buy a Ferrari Challenge car. However, he found that the Challenge drivers he met weren’t too welcoming to his outlaw attitude. The series he’d dreamed about for so long quickly lost its luster, and he was curious if there was a better way to spend his money.
AP decided to seek out a cost-conscious alternative among a more welcoming bunch. “I met a couple of the Spec Corvette guys at a Speed SF weekend and they pulled me right in. They were a bunch of renegade guys looking to have a lot of fun — so I signed up and I haven’t looked back.”
Within a few months, he’d built a budget club racer with V8 power, a large footprint, and more than enough performance to keep a driver with racing experience in twin-turbo Ferrari entertained. Best of all, he’d done it for about a sixth the price of his old Ferrari.
The C5 Corvette doesn’t have to be expensive to run. Well, it’s always going to be hard on consumables, but compared to other cars running in the 1:37s on the old Laguna Seca, this version of the C5 Corvette can’t be called pricey. Simple, too — the formula for Spec Corvette is meant to be basic so that the fields can be fairly fat without too much expected from the participants in terms of vehicle prep.
This meant that the competition would likely be close, and so AP put some more money into a knowledgeable instructor to help him get the most from his new old car. He hired Tim Moser, a respected coach with a background in Formula Dodge-Barber, LMP3, and other serious machinery, to show him how to extract all the potential from his low-downforce, high-torque middleweight.
Strengths
Building a Spec Corvette requires little. There is the sole aero item — a three-inch ducktail spoiler from Trackspec Motorsports, but the car is compliant, stable, and predictable without major aero. This is due in part to a set of one-way Penske 8300 dampers and monoballs replacing the OEM bushings. If there’s one thing which the C5 needs to be less of a transporter to the pitch and putt and more of track scalpel, it’s removing the factory rubber.
The factory brakes are fair, but the Wilwood six-pistons are a great budget upgrade, and their rotors will last a year of racing before needing replacement. Even though the minimum vehicle weight is just 3,200 pounds, the Wilwood pads can last six weekends without losing their competitive edge. Retain the stock brakes and you’ll be working on them a lot of the weekend, but the stopping power is sufficient.
It doesn’t matter if the donor car is powered by an LS1 or an LS6 — either motor shouldn’t have much difficulty making the maximum 380 horsepower and 380 lb-ft of torque at the rear wheels as per the Spec Corvette rules. Both motors are under stressed, consistent, and easy to work on.
There are two options if the car comes with the less-desirable LS1. It can use the intake manifold, heads, and camshafts from the LS6 to make the allowed power, or, if the LS1 is kept totally stock, a set of long-tube headers are allowed. The LS6 only needs to retain the factory headers to make the desired output, so it’s the better choice. Plus, its “batwing” style oil pan is broad, shallow, and sufficient for Spec Corvette usage. In fact, it’s fine for just about any application which doesn’t involve slicks and wings.
However, G-forces and sustained high-revs will still cause oil to accumulate in the LS6’s heads, and to avoid this problem, some use reduced diameter pushrods, some drill holes in the lifter trays to drain oil to the sump faster.
Those are the essentials, though there are a couple preferred changes a cost-conscious owner/driver would consider. Though differential and transmission coolers help extend the lifespan of some of these consumables, they’re not necessary to ensure consistent performance over a single race — or even over a single season. The one last potential issue in this area is, thankfully, solvable with an OEM part. The LS7’s clutch is a cheap and easy replacement for an LS6’s clutch which struggles with the increased power output. Impressively, a Spec Corvette can be built with all new components for just $40,000 — quite inexpensive for the sort of lap times it’s capable of.
Weaknesses
Now, while it would be unfair to say the car leans on its power advantage — which is enough to make it a contender in NASA ST3 — it does have some shortcomings in other areas. The braking performance is fair, though having to run the stock master cylinder makes the pedal feel a little softer and over assisted than a real race car ought to. That, combined with the oft-derided ABS system, forces the driver to learn all the braking system’s shortcomings. “You’ve gotta have the wheel totally straight if you’re going to brake aggressively,” Tim elaborates. Consider that this braking handicap would likely be worsened if the rules allowed the car to have all the camber it could use.
There is the famous lack of visibility to deal with, too. The combination of a low roofline, thick a-pillars, window nets, and a halo seat makes it tough to get a sense of what’s around you. Factor in the C5’s long overhangs and somewhat vague steering, and it might not be the easiest car to place precisely.
Nevertheless, that’s a short list of shortcomings for a car with so many strengths. Tim’s coaching and Speed SF’s open lapping groups have helped AP feel at ease in the car. “We used the last event at Laguna for passing practice since we’re usually up front at race weekends and don’t get enough naturally. Everyone we drove with was courteous and aware, which made it easy to run nose-to-tail for several sessions that day.
We loved the low-key atmosphere; normally someone complains when you’re driving in such close quarters with someone else. We didn’t get any of those problems with Speed SF, and we got all our time thanks to every session running on-time.”
No major mechanical issues, close driving with plenty of opportunities to practice managing traffic, and a strong series of lap times in the low 1:37s made their last training weekend at Laguna Seca a total success. We hope Tim and AP join us again and give us a demonstration of racecraft in one of the best performance bargains around today.
AP plans to start renting these cars out on an arrive-and-drive basis to those interested in the coming months.
Joe’s M3: Proving His Potential
Joe McGuigan was committed to paving his own path and suffering the setbacks which come with developing unloved cars, but eventually he had to capitulate and try one of the best developed cars around.
He hasn’t regretted joining the E46 tribe.

When building a track car, it’s almost always easier to take the paved path. Picking a platform that has been thoroughly developed, with available parts for every possible problem and associated forums filled with information help get the driver to the track without much wrenching.
Not that ease was the main reason Joe McGuigan decided to add an eighth car to his collection — he did that because his friends urged him to try the car he’d avoided for a while. They were tired of watching him struggle with his trailblazing passion projects. They said he’d be able to save himself time if he just joined the tribe and bought an E46 M3.
When Spencer Kimball decided to sell the E46 he’d built for his father, whose injuries prevented him from enjoying it, half of the greater NorCal track community flooded his inbox. Spencer had already proven he knew how to put a seriously quick M3 together, and this example checked just about every box a track car needs to. Plus, the price was impossible to argue with. It would make some track rat a very happy owner soon enough, but an iconoclast like Joe? Not likely.
He was well aware of the M3’s potential, but he never found it interesting enough to build one himself. He preferred the challenge of developing a less-loved car, and always found the E46 M3’s competence a bit boring. Too easy to drive quickly, too easy to build. Not enough of a challenge for a man trying to prove a point.
However, the long list of primo parts and the low, low price were too tough to ignore. Joe had to accept the “boring” car for the simple fact that he would no longer be able to handicap himself with a sub-par chassis. “I could show people how fast I really am,” he added. Rather than prove a point as a builder, he could prove himself as a driver.
He mulled it over for a few days before pulling the trigger. Picking it up on the way home was the easy part. Driving it back to his crowded driveway, it dawned on him how big a task he’d set for himself: “Now I’ve gotta put my money where my mouth is and build a really fast car,” he said.
Fortunately, the car was already well on its way towards perfection. Spencer had big plans for the build and sank a good amount of money into making it fast, reliable, and fun to drive. The short list includes:
Shaftworks USA coilovers with 500/750-lb springs
Custom Drexler-style 1.5-way differential
4.10 gears
SPL arms
Supersprint V1 header
CSL intake
HTE tune
E90 GTS rear wing
Bimmerworld diffuser
Bimmerworld 3” exhaust
PFC ZR45 BBK
APEX Wheels 18x10" ET25 Forged VS-5RS
Those and a few minor mods were all Joe needed to set some competitive times. The first track day was a few days after pickup, so he only had time for an alignment and a fluid flush. Nevertheless, its first outing in his hands, a two-day event at Buttonwillow, was a success.
He found it fast and forgiving, with a linear power delivery and direct steering. Those qualities, plus a hint too much understeer, helped Joe get on top of the car in a session. By the end of the first day, he lapped Buttonwillow 13CW in 1:56.3 — on an old set of Toyo RRs, no less. The predictive timer showed an optimal lap a half-second faster which, funnily enough, is one tenth shy of his best-ever time at 13CW in his well-developed IS-F.
He’s already sussed out its shortcomings and drummed up a short list of solutions which he plans to implement soon. Being able to knock out problems quickly with the support of a vast market is one of the reasons going with a well-loved platform makes sense. “I plan to move pretty quickly with this build. Who knows? I might sell it next year,” he laughed.
The brakes are capable, but the pads might need to be changed as the initial bite wasn’t strong enough to give him much confidence. The spring rates are too low; the owner before Spencer had specced them for autocross. It’ll receive MCS two-ways, a TC Designs cage, reinforced swaybar brackets, and full Zebulon/Buildjournal aero in the next couple months.
But the bones are good, as they say, and it’s already fast enough to aim for some of the times set by friends and colleagues in the E46 scene. While he hasn’t given up on his IS-F, he’ll fixate on beating the established BMW benchmarks for the time being.
Andrew from Buildjournal has taken his E46 M3 just about as far as anyone on the West Coast has, and his car can turn a lap around 13CW in the 1:49s. “I’m sure its capable of something in the low 1:50s with weight reduction, a better setup, and full aero,” Joe declared. There’s no reason to doubt it.
The potential is obvious, the build is nearly finished, his connections are eager to help him, and all he’s had to suffer is a little boredom. The E46 might not pull at the heartstrings like some passion projects, but he can’t deny the potential that the project holds — and the fun he’s already had with it — has caused him to change his tune.
Passing Etiquette: Making Space and Saving Face
Passing and braking are the last two things a driver learns to do well. We’ve broken down a series of basic rules to follow to help learn how to make the pass stick and how to do so safely.

Overtaking is a tricky business, and learning how to pass decisively and safely takes time and practice. It pays to err on the side of caution — especially with unknown drivers. After all, squabbling for position isn’t the most judicious thing to do when there’s no prize on the line. Nobody wins a track day.
As a general rule in racing, the overtaker must present themselves alongside the driver in front — typically with the overtaking driver’s front wheels ahead of the overtaken driver’s rears before the turn-in point. This way, they’re able to see the other driver through their peripheral vision. Studying one’s surroundings and knowing where other cars are at all times is necessary to become a capable track driver.
Of course, this is a rule followed in wheel-to-wheel racing. With Speed SF, the passing car must have its front wheels in-line with the passed car’s front wheel before the beginning of the braking zone if they want to attempt a pass. It’s worth giving everyone a little more room since nobody can truly win at a track day, after all.
Our aim is to give all our drivers their own space and help the faster drivers safely navigate the slower traffic so nobody gets held up.
To give assertive advanced drivers the leeway to pass freely while allowing novices time and safety to ease their way into it, we have outlined some hard and fast rules for our various run groups. For those groups with stricter passing rules, like Green and Blue, the process of passing is made as simple as possible.
Novice Group (Green)
Responsible novices dedicate most of their mental energy to driving their own car, so they likely lack the bandwidth to watch their mirrors while driving. For this reason, we only allow passing on the designated straightaways — never through the middle of a corner — to simplify the mental burden. The courteous driver being passed should lift off the throttle to make life easier for the passing driver. This really helps when overtaking in a Miata.
When the driver being passed decides to lift off their throttle, they give the passing driver more room to complete this overtake prior to the braking zone, which is our second requirement. The passing driver should not be pressured into squeezing themselves down the inside at the turn-in point. Just because someone, especially a novice, gives the point by does not mean that a pass is possible; the passing driver must carefully judge whether it is going to work. If it’s doubtful the pass can’t work, back off — nobody wins a track day.
Generally speaking, we like the driver being passed to allow the passing driver to rejoin the conventional driving line before turning in. If they insist on turning into the corner from an inside line (ie. a line closer to the apex than the standard line), they must navigate a shorter radius and therefore reduce their entry speeds accordingly.
Because the novice’s situational awareness isn’t as great as a regular who instinctively checks their mirrors, we require the passing driver to wait for a specific gesture from the driver ahead. By leaning their left hand out the window (or right in a RHD car) and pointing at the portion of the track they’d prefer the overtaking driver to use while passing, they give a sign of recognition and avoid confusion. Wait for a clear signal, and preferably before a longish straightaway — it’s safest and easiest to pass there.
Intermediate Group (Blue)
Even with their experience, we want members of blue group to follow the same passing rules as the members of green.
HARD RULES: GREEN/BLUE
Point-by passing is required at all times. Under no circumstances is passing in the corners allowed, and passes along the straights must be completed before the braking zone.
Point-by Recommended/Mixed Group (Yellow):
After a dozen days or so, driving alongside others at a quick pace is no longer terrifying like it once was. We try to encourage these drivers to be assertive with their car placement so as to begin the two-part process of an advanced pass. Both parties must be aware of one another, and as long as there’s enough room to overtake safely, we allow passing without a hand signal. Though a point-by is still recommended to make sure everyone is aware, it isn’t required.
There are other ways to communicate reaching an arm outside the window. For instance, the driver being passed taps their rear-view mirror prior to the turn-in point (a common acknowledgement). This indicates that the driver attempting the pass is seen and will give way. The driver ahead can also offer a corner without signaling by slowing than necessary before turn-in, usually off the ideal line. If the driver behind sees the “door opening” and the driver ahead taking an odd line slowly into the corner, they will know they’ve been given a chance to pass.
HARD RULES: YELLOW
The fundamental skill required to run in this group is strong situational awareness. Drivers are allowed to pass anywhere, but only at a moderate pace. Point-by passing is recommended, but not required. Exercise caution and make sure to read the driver ahead before attempting a pass.
Open Passing Group (Red + Gold):
Highly experienced drivers aren’t protected by such rules, which means they need to read the subtler signs of a driver giving way, learn how to pass decisively, and how to present themselves so as to be seen.
To run successfully in the Open Passing Group, you must know how to improvise with car placement while keeping the general level of grip in mind. Even while driving through a corner side by side, both drivers must be able to react and, hopefully, anticipate the other’s move.
Of course, open passing doesn’t mean fighting for position like it would in a true race setting, but the increased level of competition typical in this run group
Assuming both parties can recognize each other’s position on track and drive in harmony, these sorts of overtakes can be done safely. They do, however, require a good deal of spatial awareness, decisiveness, car control, and forethought. For that reason, we only allow drivers with over twenty track days under their belt (or those holding a racing license) to join this group.
HARD RULES: RED/GOLD
Twenty-plus track days or racing license needed to partake. Must be experienced with open passing. No passing restrictions as long as drivers exercise good judgment.
Final Thoughts
Cooperation is the name of the game, so try to wait until a definite sign is given before attempting a pass. Make sure there’s adequate grip available to take a tighter line than the conventional line if that’s what the situation requires. The tighter the line, the more deceleration prior to the corner is required. Trailbraking helps here.
If a train of cars ahead makes life difficult for a faster driver bringing up the rear, they’re advised to pit momentarily to establish a gap. This makes life much easier and offers a better chance of achieving a personal best.
When deciding whether or not to attempt an overtake, remember that the passing car is always responsible for ensuring a safe pass. Even if the car ahead closes the door on the driver behind, it’s the latter’s fault. Leave a little space whenever possible and never squeeze somebody on a track day.
Keep eyes up at all times, scan the environment for faster and slower cars both and behind, and try not to fixate too much on rolling speed into the corner during an overtake. Instead, prioritize a strong exit. Well, the beginners should try to do this to avoid sliding off when overtaking on the inside. The experienced drivers know that, in racing, sometimes getting ahead of the driver in front is all that’s needed; an overtaken driver can’t always respond if the overtaking driver exits the corner slowly. Again, that’s racing, and this is track day driving, where the objective is to bring the car home in one piece.
Lastly, remember that there’s nothing to win here. Track days exist to help people gain experience running independently, so giving way to a faster driver when they’ve demonstrated superior speed is a mark of maturity. Yes, it might sting, particularly if they’re in a much slower car, but leave some room for humility and open the door — following a faster driver closely can be the best sort of instruction anyone can get.
Thomas' Corvette: In Good Company
In only two years, Thomas has learned more than most will grasp in a decade of track days. Having a solid, dependable C5 has helped him put in his time, and having Elite Performance as a resource has made fine-tuning the car so much simpler.
Finishing out his senior year of high school, Thomas DiGioacchino listened to a friend’s suggestion and scrounged the money together for his first track day. Crap tires, decent weather, and a near-stock Mustang GT were all he needed to find that thing that’s been steering his life for the last five years.
Thomas decided to pursue the mechanical side of things and enrolled in Ranken Technical College’s High Performance Technology course with a focus on Chevrolet LS engine design.
That emphasis allowed Thomas to build a motor for a car he hadn’t yet bought. It began with an iron-block LQ motor and LS1 heads, and as the LQ block only displaced 5.3 liters, he bored and honed it out to 5.7 liters to fit the LS1 head. With forged pistons and rods, oil pan baffles, and the other pieces that made it a 500-horsepower workhorse, he unknowingly set the tone for the rest of this build.
The car itself came next. During his final year at Ranken, he found himself a base 2002 Corvette within his price range and tucked it away in his side yard until graduation, when he loaded up his truck with his furniture, his motor, and began his drive from Missouri to his hometown.
Back in San Mateo, he reached out to his then-limited network for car parts and, with some luck, gainful employment as well. As he’d relied on Elite Performance to direct him towards a few bolt-ons for his Mustang, they were the natural resource to consult. One day, while speaking to Elite’s Melody Cannizzaro about getting his Corvette aligned, she provided up with a job opportunity. He didn’t have to think twice.
Working with Elite gave him access to one longtime customer who happened to be offloading some go-fast bits from their recent Corvette build. Thomas was able to grab a set of Titan 7 T-S5 wheels for peanuts, and then came big brakes, bushings, and a bucket seat. Soon, the plans for keeping the Corvette tame and civilized went out the window.
Wisely, he went for safety equipment next, and decided that this car would only help him become a truly quick driver if it was reliable first and fast second. “I knew that seat time would be the priority if I was going to run with guys like Gary Yeung,” he said.
That said, it would be silly not to make use of the big motor sitting in his parent’s backyard. Soon, it found a new home in the Corvette’s engine bay, and Thomas took the half-built C5 to its first track day, where it ran without a hiccup. It ran well the second day, too, as well as the third. Clearly, he’d paid attention in class.
Aside from the minor repairs any twenty-year-old car needs, it was the epitome of dependable. His focus was on learning to drive the car better, but, to his credit, a C5 on stock suspension does leave a lot to be desired. It would lean excessively, and under trail braking, it had a habit of snap-oversteering.
After several months of saving, Thomas bought a used set of JRZ two-ways. While he was at it, he pulled and refreshed the entire drivetrain, then upgraded the springs and clutch packs in the OE LSD. Those modifications made the Corvette much more progressive at the limit, regardless of whatever cheap tires he happened to be running.
When he found the time to fine-tune the suspension, he increased the rake to increase rotation at corner entry. A square 295-35/18 setup was the cost-conscious tire option, and he stretched every set until the cords showed. Still, the car was mostly neutral with a hint of understeer in the faster stuff thanks in part to his APR GTC-300 wing.
As his confidence grew, he started to recognize that driving around on worn rubber was no longer the training tool it had been, so he sprung for a set of AR-1s and turned his first sub-two-minute lap at Buttonwillow 13CW. “I had to fight it the whole way around, but I got 1:58. A sloppy 1:58, but still,” he said.
Good tires helped, as did having a hare to chase. With Gary Wong driving his S2000 off into the distance, Thomas was able to see where he could push harder than he believed was possible. It’s a huge help having an experienced driver luring your outside your comfort zone.
Logging that first milestone lap gave him the confidence to try the Speed SF Challenge the next weekend at Thunderhill’s five-mile configuration. He did his homework and studied several record laps, focusing on curb usage. With Gary Yeung giving him some basic feedback the day of, Thomas saw his lap times fall by as much as four seconds. In the end, he was able to clinch third place in S2 — just half a second behind Kevin Schweigert in his BMW M2.
That success turned Thomas into a sponge. His subsequent lapping days have been spent studying data and having the experienced drivers like Joe McGuigan critiquing his onboard videos. “Joe’s been a huge help; giving me pointers on which gears to use so I can put the power down more easily.” The result of this traction-conscious approach to driving is evident in the footage below:
He’s also benefited from picking a short list of prime parts. In fact, he’s never bent his Titan 7 wheels or broken any suspension parts, despite hammering curbs and dropping wheels regularly. Maybe it has something to do with emphasizing robustness with this build—a tip he picked up from his mentor, Gary Yeung.
‘I’ve learned a decade’s worth of motorsports knowledge in the last two years. Everyone’s been so supportive, and I owe my progress to all of them. They’ve pushed me to improve as a driver and a builder—especially Gary. Watching him work inspired me to raise my game, and I think it shows. My Corvette’s overbuilt, so I can push it all day. Like Mango, my Corvette is a workhorse that’s made it possible to attend almost every Speed SF event in the last two years. All I do now is change the fluids and try to find out where I can go faster.”

Thunderhill Logistics: Where to Stay, Where to Eat, How to Beat the Heat
With plenty of options for food and lodging, reasonable track fees, and plenty of ways to beat the summer heat, a successful trip to Thunderhill only requires a quick review of the information listed here.
If you’re not suited to warmer weather, the propect of spending a day in the sun at Thunderhill Raceway Park can be a little intimidating. True, there are the fair share of summer days in the mid-seventies, but they’re hard to pinpoint, and unless you’re willing to wait until the winter when the weather is wonderful, you might find Thunderhill a bit too hot for your liking. However, if you can brave the heat, the reward is worthwhile.
With an interesting variety of corners, two separate tracks that are conjoined occasionally (not often enough), great sightlines, and plenty of runoff, there’s a lot to like about Thunderhill.
While it might not have the amenities of nearby Sonoma Raceway, Thunderhill is accommodating. The nearby town of Willows features several decent restaurants, a Walmart, reasonable gas prices, and a selection of mid-tier hotels that make it possible to spend a weekend there in comfort.

470 Airport Rd, Willows, CA 95988
While gloom and doom isn’t the right tone to set the stage for one of Northern California’s most popular tracks, there are a few temperature-related concerns that should be considered—even if you’re as cool as a Bedouin. Always prepare for the heat. Bring a cooler and lots of water. You can buy ice at the track. You want to stay hydrated,.
Though a quick trip back into Willows isn’t ideal after you’ve arrived at the track, it’s only a ten-minute drive—not that there are too many reasons why you’d need to.
Food at the Thunderhill Grill is good, there are many covered parking spaces (as long as you arrive early), and the track seems intent on expanding the covered area. Thankfully, there’s an air-conditioned clubhouse to beat the heat on the worst days. Outside of the hottest months, camping at the track is an appealing alternative to the sometimes pricey hotels.
Lodging
In town, the lodging is concentrated within a couple blocks. Most consider the Holiday Inn Express to be best, though there are a half dozen alternatives when it fills, which is typical on the busier track weekends. If you’re on a tighter budget, the Super 8 offers a pleasant place to lay your head. Expect prices to nearly double on the busiest weekends.

Dining
For variety and ease, dining in Willows is your best bet. The Black Bear Diner has hearty fare, plenty of fast food, a Round Table Pizza, and, for a slightly nicer dinner, Casa Ramos is the preferred restaurant. It’s not a proper Thunderhill trip without a few margaritas at Casa.
For those who want something more upscale, there are a few upscale options outside of Willows. Nearby Orland has two interesting spots: Farwood and The Hive. The former’s bar is definitely worth a visit. Thirty minutes away in Williams is a renowned restaurant called Granzella’s, as well as La Fortuna Bakery, which has exceptional burritos.

General Amenities
Being out in the country has its perks. Willows is relatively quiet and very safe. However, it does get quite dark early at night, and the lights turn off earlier than some expect them to, so if you’re planning on changing your wheels for the drive home, don’t wait too long.
For basic auto parts, there are two places to try in town: O’Reilly’s and NAPA. However, their in-stock selection is limited. Gas is slightly cheaper in town—a Chevron and an ARCO are popular spots—but a portion of the price paid at Thunderhill’s pump goes towards maintaining and expanding the circuit. In fact, the management has done an exceptional job in making sure the track is healthy and thriving, which is why it’s no surprise that its become one of the most popular circuits in the area with far more track days booked by any outfit than any other track.

Whether you’re going for a spartan day trip or a luxurious weekend, there are several approaches to take to suit your needs. As one of the more accommodating tracks in Northern California, Thunderhill Raceway Park is one that is easily enjoyed, and despite the warning about weather, visiting is rarely exhausting. Just make sure to bring a few gallons of water, and, on particularly hot days, some higher octane fuel (available at the track pump) might keep your car from pulling timing as hard.
Speed SF Challenge Laguna Seca: New Surface, New Records
New pavement and stellar weather meant our fastest drivers pushed harder than ever before at our latest Speed SF Challenge event.
Ideal weather and a massive turnout of thirty competitors at the last round of the Speed SF Challenge guaranteed some action. Sure enough, we saw new records in several categories. Though some of the newfound speed was due to the recent repave, our Challenge drivers were in stellar form that weekend, and their onboards prove that.
In S1, Steve Melson and his Audi R8 broke the S1 record that had been standing for five years, set back in 2018 by Andrie Hartanto in a C6 Z06. Steve took advantage of the stellar weather and logged a 1:34.081 — a new record that any driver should be proud of—in a car that looks nearly stock. Such is the performance of the second-generation R8.
In S2, Kai Anderson reset Peter Hsu’s Chevy Corvette record by seven tenths. Anderson ran a 1:34.8 to Hsu’s 1:35.7, but not before suffering through a few frustrating sessions. By the end of the day, he cooled his jets long enough to find a gap and avoid slower cars. “My main challenge was recovering from a poor qualifying. There was a good turnout for this event which was great, but it meant the morning sessions were a little crowded, so I ended up only qualifying 7th fastest overall. I recovered to 4th fastest overall in the Challenge session, so mission accomplished, but my fastest lap didn't come until lap 5 because I kept having to abort laps due to catching traffic.
I didn't really have any specific goals for the weekend; mostly just evaluating what is still a relatively new car to me on a newly resurfaced racetrack. Overall, I was impressed with both. I think the changes to Laguna really inspire confidence to push for that optimal lap without creating a different line that requires total abuse of track limits.
The Camaro is perfect for Laguna, with prodigious power, cooling, and brakes to match. There is definitely still some laptime to come from this pair. Crossing my fingers December is dry!”
In S3, Spencer Kimball put in a serious effort to try and beat Kevin Schweigert’s S3 record of 1:36.0.
“I went into this event with some reservations knowing that my M3, with limited torque, was not at its best on Laguna’s straights. Laguna is also the one local track that I drive the least, but I made sure to try and get some practice in before the Challenge weekend. I lucked out and a friend lent me his pass for an event the weekend before, where I ran a low 1:37 after a year-long Laguna hiatus. I looked over my data and saw that a mid-35.xx would be possible, but I went into the Challenge event with the goal of breaking into the 36s.
I knew that I had my work cut out for me as my main competition, Legend Brandenburg in his A90 Supra, benefits from ~200 more ft/lbs more than my E92 has. Luckily I was able to run a mid 1:36 during sessions 1 and 2, which put giving me a good spot for the challenge session. I studied my data to figure out where I needed to commit, and it was clear that the faster corners were where I could push harder to find somet time. I ended up running a 1:36.5 in the Challenge by carrying more speed through T5, T6, and T8, which was enough to make me the fastest in S3.”
In the end, Kimball was just 1/2s off of Schweigert’s lap, which Schweigert set in a car weighing 500 pounds less with comparable power levels. Not too shabby.
Gary Wong still has a little bit of work to do in the Supra to find the second between him and Dave Colbert’s 1:31.5 Group X record. The infamous purple Supra had its engine tweaked slightly to reduce power cuts, but heat is still an issue which Wong has to deal with. Thankfully, the team has a solution—though they won’t be able to use it until the next weekend.
“It was a fun weekend. I mainly wanted to sample the new track surface and see where I could push more than before. Because of how bad the stupid bump at T1 is, I wasn’t able to hit our sub-30 target times, although that had something to do with to traffic and some electrical gremlins. Because of some overheating issues, we had to lower the power level to complete the full lap. Thankfully, we know the issues and the solutions and we’ll come back stronger.”
Gunning for the S4 record, Nate Hackman’s put in an incredible 1:39.7, less than one-tenth off of Sean Yepez’s record, in what appears to be a very mildly modified car without any aerodynamic goodies. The primo parts are under the skin, though: his Ohlins TTX coilovers help his S2000 handle better than most. A last-minute setup change reduced some of the oversteer in the car, so Hackman could commit to the faster corners easily.
“Up until that weekend, I had only mustered high 41s at Laguna. With the repave running faster and a few changes to the car I figured I'd run a second or two faster, but tried not to overthink it with goals and just go have fun. Luckily, I was able to cook off a number of 39s with some definite room for improvement. I was still a tenth off Sean's pre-repave lap record which was a little disappointing, but I knew he'd come back and crush any record I set, and was still very happy to crack into the 39s with no aero and take home a win with an underbuilt car.”
In S5, Tony Rodriguez’s 1:45.2 record seems untouchable. Maybe we need another all-out MR2 to chase Rodriguez’s old S2000 down. In the meantime, we’ll have to tip our hats to our talented drivers taking advantage of the new pavement and pushing themselves hard enough to keep all the Speed SF Challenge competitors on their toes. When times continue to tumble like they have been, none of the Challenge competitors can coast, boast, or rest on their laurels.
Andy's NC Miata: How To Make 300 Horsepower In 3 Not-So-Easy Steps
Intent on keeping costs low, Andy Boskovic started tinkering on a third-gen Mazda Miata. The need for more power was clear from the start, so he first tried to swap in a 2.5-liter engine from a Ford Fusion.
Then he turbocharged it.
“After five years of ownership, I’ve learned these cars only last when they’re basically stock,” Andy began.
Some of Andy Boskovic’s friend suggested he keep tracking his E92 M3, but it just wasn’t exciting him any longer. “I’d tried a few light cars, and I liked how playful they were,” he recalled. “No matter how much power a car has, if it’s lightweight, it will always be fun,” he said. Plus, the cost of consumables and its heft kept him from relaxing. Careful not to break the bank, he started looking for something svelte, simple, and reliable.
Because of his size and his cost constraints, he bought a mildly prepped third-generation (NC) Mazda Miata. For a third-gen Miata with Megan Racing coilovers, Hotchkis swaybars, and a factory hardtop, a mere five thousand was money well spent.
If there was one unforeseen problem at this point, it was that Andy did not know quite how limited the NC aftermarket was back in 2018, but, thankfully, this car was quick and reliable enough to not need to. The car ran well in stockish trim, and no real changes were necessary for the first two years of tracking.
After getting to terms with the car, he could diagnose its few weak points. More confidence on the brakes meant harder laps and more aggressive corner entries, and those highlighted the one glaring handling issue.
Though fun, the car was a little too loose to be truly quick, and this was clearest in the faster corners. “The short wheelbase makes this car oversteer in Riverside,” he started. He first softened the rear bar, then removed it entirely. “I picked up a little understeer when I removed the rear bar, but I gained 1.3 seconds the next session on the same tires,” Andy added.
Another Half-Liter Can’t Hurt
After two years of trouble-free track days, the engine began to knock. Intent on keeping his costs low, he decided to try the 2.5-liter MZR alternative. This particular motor came from a Ford Fusion — a $200 find at his local junkyard that swapped into his car with minimal modification.
Swapping the 2.5 into the NC’s engine bay requires transferring oil pan and valve cover from the 2.0-liter to the 2.5-liter, grinding the front cover engine mount plate to allow the belt to spin without rubbing, and changing one pigtail for camshaft position sensor. Everything else stays the same; the whole harness, ECU, engine mounts work. What’s more, the transmission is direct fit.
It’s a good thing the swap was simple, because the excitement didn’t last long. After just three track days, the engine blew. Andy believes it was a lousy online tune which caused the engine to run too rich. Because he hadn’t installed any A/F meters, he’d been totally unaware of his pistons were getting washed over the first few months.
This setback didn’t deter him. In just a few weeks, Andy grabbed a new motor — one with which he would try a different approach.
Being designed for an SUV, the 2.5 MZR was never really designed to rev. The motor feels genuinely torquey—almost VQ-like—in the midrange, and calling the top-end lackluster would be generous. Extra cubes do help the car feel livelier in slower corners, but the disappointing final few thousand revs warranted a major change — even if the motor was never intended to buzz too high. With a set of Esslinger camshafts and a little headwork to enable 7,500 revs, he extended that top end to a point where things felt S2000-ish.
The 190 horsepower the new lump came along with a few complimentary additions to turn a mild street car into something focused and trailered. Version 2.0 sported a stiff set of Feals, a full cage, and a lot of unsightly bare metal. The stripping process brought the Miata’s weight down to 2,330 pounds, which is not much heavier than a Spec Miata, but with an additional 70 horsepower and 100 lb-ft of torque, those power improvements made the Miata much more versatile.
Compliance is Key in Southern California
The 13K/10K spring rates didn’t suit the bumpier tracks he frequented, so he consulted Karcepts, who tuned the NC cars which ran in the Playboy Cup from 2008-2013, suggested he try a softer setup. They supplied him with some MCS 1-ways, which came along with 10K and 7K springs. The improved compliance netted him a whole second on the same set of tires. Clearly, he was on the right track, though the setup was far from perfect.
In an attempt to try and minimize some of the car’s tendency to oversteer in high-speed corners, Andy cranked the front dampers and left the rears on the softer side. “It rotated when you wanted it to and the rear stayed stable. Still, when the rear finally let go, it was not very progressive.”
“I was never that interested in running aero because I didn’t like that Fast and Furious-look, but I couldn’t accept the snappiness at the rear, so I tried a wing.”
Following the first on-track session with Racebred Component’s 4” front splitter kit and their GT rear wing, Andy forgot entirely about looking like an attention-seeker. The aero bump immediately chopped 2.4 seconds off his previous best at Buttonwillow. Other than adding the wings, nothing else had been done to the car.
The unfortunate byproduct of greater stability in the fast stuff was a smidgen of push. Not so much to keep him from attacking, but just enough to feel the Miata was no longer the playful, adjustable thing it used to be. Cleverly, Andy chopped two holes in his front fenders and topped them with a set of Cockroach Concept louvers. These relieved pressure from the fender wells, improved front downforce, and helped the car regain its natural pointiness — now tempered by the rear wing. It’s extremely neutral in both fast and slow corners, and it’s still soft enough to soak up big bumps.
The performance of the front relative to the rear encouraged Andy to see if he could further strengthen the car at turn-in. With a five-inch splitter and front spats from Racebred, the front end was electric, but more importantly, he could still keep the car balanced aerodynamically, though that required doing something many Miata owners might be hesitant to do.
Trim Fast
Without much torque, Miatas have to avoid as much drag as possible, hence the preference among many owners to run only as much wing angle as necessary. He was conscious of overslowing the car on the straights, but he needed a more neutral balance to push hard. By increasing the angle of attack at the rear wing, he found a confidence-inspiring aero balance that, as he learned, improved the car’s cornering performance enough to incur a little drag.
For someone accustomed to trimming his Miata out as much as necessary, this was a shock finding. “I was losing about three miles an hour on the straights, but the car was so much faster in the corners that I saw a net benefit to this high-downforce configuration.”
Content with the aerodynamic and suspension settings, Andy started on the one area he was reluctant to try. Between a bad tune and his habit of revving the tits off his motors, he went through three engines —one 2.0 and two 2.5s — in the four years he’d had the car. Still, seeing a Mustang or Porsche walk away towards Sunset was a source of real irritation, so he decided to turbocharge his MZR.
Unfortunately, the aftermarket hasn’t provided NC owners with many different turbocharging methods to try. Yes, the MZR has been turbocharged for competition use, but the AER-built motor found in IMSA prototypes and Indy Lights cars is a far cry from the factory 2.5-liter.
Long story short, the turbocharging process has been, as Andy put it, “a world of shit.” The problems with overheating and oil starvation killed one motor quickly, and the current engine, built to maximize torque and keep the revs reasonably low, is still getting the bugs worked out.
However, parking lot tests have demonstrated real grunt, tractability, and promise. With a standalone ECU, a reinforced gear hub in the fragile gearbox, and a smaller wastegate spring, he plans to have a dependable 260 horsepower from 3,500 - 6,500 revs.
“I believe revving the 2.5-liter engine to 7,500 shortens the lifespan to forty track days or so. The turbocharged engine doesn’t need the same revs to make power. If you cap the revs at 6,500 and power around 260, I think it could last. I’m not betting anything on it, though,” he laughed.
Why Trackday Coaching Matters
When Eric Preciado got serious about his racing, he hired a driving coach to help him shed some of the bad habits he’d picked up in autocrossing. At the end of his first day with Joe McGuigan issuing instructions, Eric was lapping nearly five seconds faster than he had previously.
Although Eric Preciado had experience in a variety of cars in e-sports and some track time in the real world, he sensed he needed some guidance or, at the very least, some structured lessons to help him advance as a driver.
Being a fastidious and goal-oriented person who likes to monitor his progress in everything he does, Eric Preciado figured a coach would help him analyze and understand his driving technique a little better. He hired colleague and local ace Joe McGuigan to guide him along, and as Eric realized, a good coach can offer much more than basic lessons in theory and technique.
Laying a Foundation
Joe’s opinion as a professional instructor was that, as opposed to Eric’s Cayman or another unforgiving car, a Spec E46 would help Eric advance the fastest. Plus, it was a company car, so it was easy for Eric to borrow it for a day.
Spacious, forgiving, torquey, quick, and easy on consumables, it’s fast enough for most drivers and a great way for drivers to learn their craft comfortably. Because of its progressive breakaway, it gives a coach plenty of time to identify a mistake made by their student long before it happens.
With the proper car selected, they started their day at Thunderhill West going through some rudimentary theory. Joe’s basic approach is to help a novice build a foundation of good habits that will keep them safe, that they can continue to build upon, and that help explain the physics at play. With Eric, it began with a detailed explanation of the racing line, including braking and turn-in points.
Though Eric had a basic understanding of these concepts, he had developed some habits in autocrossing that do not transfer well into the world of road racing. “I didn’t recognize it, but I was shocking the car with really rapid steering inputs. This usually works in autocross, but not at higher speeds,” Eric recalled.
Then there were the braking points. Most initiates struggle to realize just how hard and late into the braking zone a well-sorted car can stop. It’s a forceful touch—easy enough to understand given some instruction—but the timing and the release of the pedal take far more sensitivity, and that’s something an experienced, sensitive driver can assist their pupil with.
Eric listened intently and put those pieces of information to good use. With his newfound confidence on the brakes and slightly cleaner lines, Eric set a baseline of 1:31—a respectable time at Thunderhill West and a full two seconds faster than he was able to go on his own previously.
As impressive as that drop in time was for only one session of work, Joe knew that he’d have to encourage Eric to push a little harder in order to find more time. To convince Eric that the car could take much more abuse, Joe took the wheel for two laps and demonstrated how late he could brake, how much entry speed he could carry, and how sane and composed it would be, despite all the additional loading. Even with two heavy occupants, Joe proved this well-sorted Spec E46 could lap Thunderhill West in 1:25.
This demonstration was not given without one firm reminder: this is what the car is capable of when it’s driven properly; going faster isn’t as much about courage as a novice might think. Muscle memory can be acquired from the passenger seat, and when Eric left it to get back behind the wheel, he had a few new things he wanted to try.
Following the First Leap
Now confident the car could brake later and carry much more entry speed than he thought was possible, the coach became vital. Now asking more from the car and making inputs which weren’t all that different from those he made earlier in the morning, the Spec E46 didn’t quite stick where it had before.
Resolving this oversteer issue began with the typical countersteer-pause-recovery process so many of us are familiar with, but need a little fine-tuning to make it second-nature. After a session on the skidpad, Eric felt comfortable catching his little slides. “Not only did I get an idea of what the limits were, but I learned how to deal with going over the limit. Rear end steps out? A nice and controlled throttle application with the appropriate amount of countersteer will solve that,” he noted.
It’s a recognition of the subtler mistakes that a student makes which makes a coach sitting onboard so valuable. Joe, seeing that Eric was lifting off the throttle for an extended period—a normal side effect of carrying more entry speed than is comfortable, and so he had to make a critique.
“I could see that his long lift off the throttle was destabilizing the car, so I told Eric to start using a little maintenance throttle in Turn 6 to help settle the rear end,” Joe said. Not only was this to help his student progress safely, but to help Eric understand that a little oversteer is nothing to worry about—it can even be his ally in cornering. Talk about a shift in perspective.
Along with the softer steering inputs, more assertion with the brake inputs, and a careful weight transfer that helped give him confidence in the faster corners, Eric could start to feel comfortable enough to analyze his driving and use a little bit of rear rotation to help him corner faster. Prior to that, he was driving cautiously and dedicating most of his concentration to avoiding an oversteer moment.
To have both peace and presence of mind is worth the cost alone, but it’s hard to brag about those things at a bar with your buddies. Thankfully, Eric had a new stat he could hang his hat on: he managed to get down to a 1:28.2 by the end of his final session—that’s an improvement of nearly five seconds in just four sessions.
Solutions for the Time/Budget-Limited
Not everyone has the flexibility or the budget to arrange for in-person coaching, but those shouldn’t prevent them from getting a qualified professional’s perspective. Fortunately, there are two ways drivers can get some instruction from the comfort of their homes at a time that is convenient for both student and instructor.
“Video reviews are something I enjoy doing as they allow me to give relatively quick and easy to digest notes for a new client to understand, while giving me a sneak preview of their habits—both good and bad—that I can use for our future in-car coaching sessions.
I also do this with some of my regular clients as well, as timing doesn’t always work out for me to do in-car coaching. Obviously, driving a track I am familiar with helps, but I can still provide notes even for a track I haven’t necessarily driven in real life, but I can still give input on basic lines and inputs the driver is doing with the car. However, there is another form of digital coaching that I utilize, which even allows me to do lead follow, and that is sim coaching.
I prefer working with Assetto Corsa as the track and car availability is very vast thanks to an active modding community. The joys of doing sim racing is that I can be live chatting with a client while watching the live feed via Discord or other streaming service. We can even do lead-follow together, practice passing and defending, and walk through setup changes to improve the car that client's driving,” Joe elaborates.
Undebatable Data
For the advanced driver, it’s data review that makes the difference. The difference between an exceptional lap and a good lap is almost imperceptible, even to the trained eye. Studying data, as is possible with the information collected by an AIM SOLO or similar device allows them to get into the nitty gritty. Ideally, they run a demo lap with Joe driving, then overlay the clients lap and work on the low hanging fruit before focusing on those last couple tenths of a second.
This sort of review will help you recognize that, for instance, braking later into a corner followed by a long straight will not always yield the best overall time. Though theory claims that you should prioritize the exit in a corner leading onto a straightaway, the top speeds and delta shown in the data reveal just how much a banzai-braking attempt is actually paying off. Unlearning bad habits is made easier when the student is presented with irrefutable evidence of their detrimental effects.
Experience Reducing Energy Expended
Though it’s mostly changes in technique that aid the novice driver the most, the intermediate and advanced drivers can benefit from a coach’s understanding of a particular car and what it needs in terms of chassis set up.
The E46 was set up for sticky Hoosiers, but because they’d fitted it with milder RS4s that day, Joe made a few tweaks to the MCS 1-way coilovers after his session; softening the bump and rebound to suit the level of grip offered by the RS4s.
Breaking Past Imaginary Barriers
“While I understand the physics and vehicle dynamics behind driving at the limit, I didn’t know them physically. My perception of what the limit was has always been flawed and defined by other imaginary circumstances such as wrecking a car or not being able to afford replacing a bent tie rod.
Coaching allows you to understand where the limits really are, how they feel like, and how to drive near or past them. With Joe, I was put in a position to experience those things safely, which gave me the confidence to push past my own mental blocks holding me back from becoming a better driver,” said Eric.
While some might think the extra expense is unnecessary, nothing—not better parts, not better weather, not even weight reduction—will make as big a difference to lap time in one day of driving. Frankly, the pride that comes in figuring things out for yourself is not worth the time and expense—and those discoveries are harder to make as the driving level improves and glaring mistakes become subtle imperfections. Bank on a coach with a good reputation and your bank account will thank you for it.

Justin's IS F: Rekindling An Old Romance
After a seventeen-year sabbatical from racing, Justin Munoz picked up a capable sedan that, over the last few years, has helped him fall back in love with motorsport.
Justin had his first shot at track days back in 2003, but that one afternoon at Thunderhill East in his 7th generation Celica GTS would be the last time he’d set a tire on track for nearly twenty years. Still, he managed to set a 2:15 at that event, so at least he had demonstrated his chops in the process.
Then life intervened. Marriage, children, divorce, and other financial priorities forced him to put his racing aspirations on the back burner for the better part of two decades. During his seventeen-year sabbatical, he dabbled with motorcycles and a third-generation Mazda RX-7, but never took either to the track.
Once the kids grew up, Justin saw an opportunity to return to the track. Then the pandemic hit, and to make matters worse, he lost his job. For a bitter moment, his chance to return to tracking seemed to fall just out of reach. Rather than fall prey to despair, Justin began consulting, then went into business with a close friend. Fortunately, that career move proved lucrative.
So much so that he could suddenly consider several supercars. “I debated between an NSX and an R8,” he said, “until my fiance made a suggestion. She said, ‘Instead of dumping a lot of money into one of those, why not buy a cheaper car you can modify your own way?/”
Cogent question. Justin started considering the criteria he was looking for in a mid-tier car. Reliable, large displacement, naturally aspirated, and as he thought longer and longer, he grew to like the idea of a four-door. He cast his mind back to a stoplight-to-stoplight race during the time he was driving his RX-7. “I remember an IS F totally smoked me,” he recalled. Seemed like the big Lexus sedan fit the bill.
And so he started scouring the more reputable classifieds. There wasn’t much he’d find that seemed like a suitable candidate. Ironically, it was only after four fruitless months that he capitulated and started scrolling through the Craigslist pages, where he only spent a few minutes before finding the perfect car. Better yet, it was parked just a little down the street from Justin’s house.
With only 77,000 on the clock, one owner, and complete service records tucked neatly away in a binder, this immaculate machine held a lot of promise. However, Justin being a prudent guy, he had his friend at Magnussen’s Toyota inspect the car to be certain it was the gem it appeared to be. After performing the PPI, his friend told him, “If you don’t buy this car, I will.”
Justin didn’t give him the chance. With his new acquisition sitting pretty in his garage, Justin began researching what a track-ready IS F had over his bone stock example. At the very least, any set of performance shocks and brake pads would keep it from falling on its face. However, Justin being well connected in the industry, he splurged for the fancier stuff: Carbotech XP10 pads, Michelin PS4S, and HKS Hipermax coilovers.
His return to the track—Buttonwillow this time—after seventeen years away was comically carefree. “It’s just like riding a bike,'' he told himself. He set out brimming with pride and excitement, but he quickly realized just how tire technology had come in the last two decades—and how rusty he truly was. After dropping two wheels at the exit of Bus Stop, he reigned in some of his exuberance and started to drive much more sensibly. “It was eye opening and humbling, to say the least.”
A trip to Thunderhill West a few weeks later was not only humbling, but dispiriting. The IS F’s inability, so he thought, to handle the constant barrage of corners put him in a foul mood. In fact, he was considering abandoning the platform that day at a somber lunch.
Post-meal, he found a little more encouragement from the car and managed not only to stick in a respectable 1:33, but he executed a spectacular pass around the outside of Joe McGuigan, who was then riding shotgun in a student’s car.
Joe, another proponent of the Lexus sport sedans, could see by the IS F’s bucking-bronco body language that the damping was insufficient for the workout Justin was putting it through. Following Joe’s recommendation, Justin reached out to Shaftworks and ordered a custom set of coilovers to suit the heavyweight.
“That’s when it spiraled,” he laughed. Along with those new coils, he picked up Ultra Racing chassis braces, FIGS arms and bushings, Sikky swaybars, and a few other items that stiffened the chassis to the point he could drive the car as aggressively and accurately as he hoped. Of course, the newfound cornering forces required some additional core support for the driver, so he threw in a Recaro Profi XL.
It didn’t take long before he had to fortify the platform again. With all the extra energy he was putting into his wheeling, the tires and brakes were struggling to keep up. “I tried RT660s, but they got greasy too fast. I spoke with a Camaro owner who recommended Goodyear Supercar 3s and figured I’d try ‘em.”
Wrapped around a new set of Momo Catania wheels measuring 18x10”, he was thrilled with the newfound consistency these new tires provided him. “Once they’re warm, they remain at the same temperature for the rest of the day—it’s a little like cooking with a cast iron skillet.”
Naturally, the added grip strained the binders to the point of developing stress fractures and mirroring some. In their place, Justin added a set of GS F calipers, bigger OEM Brembo rotors, and a set of Carbotech XP12s to bring everything up to a dependable par.
Swept away by the rate of development and the improvements he was enjoying, Justin asked himself, ‘What could it hurt to have a little more power?’
With a custom tune from Tuned by LOI, full bolt-ons, and a tankful of E30, the 5.0-liter made a very healthy 438 horsepower and 401 lb-ft at the rear wheels. To make the most of this bump in grunt, he added a Sikky carbon driveshaft and an OS Giken 1.5-way LSD.
With the level of funding he’s put into this machine, Justin decided to make this former heavyweight into a svelte track-only sedan—and is leaving it to the pros to help realize its potential. Additional cooling, a welded cage, and some lightweight body panels are just a few of the additions Race Factory will be making this summer.
If all goes to plan, he’ll be trailering this beauty to several shakedowns next year before entering in Global Time Attack, where he hopes to make a splash in the Street Class. With the good luck he’s had thus far and the wise McGuigan to guide him on his way, he has a shot at making some waves with this (perhaps former) heavyweight.
“I just want to thank my family, friends, and the car community for being so supportive. Without all three, my return to motorsports wouldn't have been anywhere as fulfilling as it has been.”
Nic's Porsche 911: Take a Chance on the 996
Take a risk and keep it simple. Nic Gerardi’s shown us that the 996.1 Carrera’s a great track car with the right modifications. Stout, light, full of feel, and very reliable, it might be worth the chance of a bad IMS.
Some of us get our start tracking in unusual equipment. Nic Gerardi began with a Volkswagen Jetta—a car which, by his admission, was “never really made for this sort of stuff.”
That wasn’t quite the cask with this 996.1. This 2001 Porsche 911 was, as he put it, “Just OK.” Being a base C2 Carrera, it was quite soft—more of a grand tourer, really. Running all-season tires didn’t help much there, either. “It pushed so much; it really wouldn’t leverage the rear,” he noted.
The fact that it was so soft allowed him to hustle the car over the curbs in a way he never felt comfortable doing in the Jetta. Part of that sense of security came from the general feeling of robustness he had when driving the 911—a car he believed to have more potential.
Wisely, Nic recognized that the driver was the limiting factor at that stage, so rather than begin by adding performance modifications, he decided to choose a collection of safety improvements. A four-point DAS Sport bolt-in rollbar, a Recaro pole Position ABE seat, and an OMP six-point harness gave Nic the sense of security he was after—a wise choice that helped him push the car to the limit and understand the Porsche’s demands.
After making the safety upgrades, he improved the wheel and tire combination—again for similar reasons. The wider set of APEX SM-10 wheels and Continental Extreme Contact DWS worked to help him learn the Porsche’s peculiarities. “I didn’t want to over-tire the car early on, because running high-grip tires can, up to a certain place—maybe eight-tenths, allow you to practice bad habits. I wanted to know it more intimately before I threw on some R-compounds. Plus, these tires are usually pretty communicative, so they made it a little easier to learn the car.”
There were three more factors needed to achieve a greater understanding of the 911. The first two were consistency and durability. For those factors, he installed a set of stainless brake lines and Pagid RS29 pads which, even at Laguna Seca, would not fade. The final touch: improved body control and sharper responses. Though some might not think it, a stock, base 911 built during the Clinton Administration is a pretty floppy thing.
That’s why it took relatively little to get the car feeling five times more athletic than it had stock. Along with Function First semi-solid engine and transmission mounts, he replaced all the suspension bushings with stock parts, then added a mild set of H&R Street Performance coilovers. In conjunction with factory GT3 sway bars front and rear, these few tweaks made a vast difference in the way the car would rotate—how it “leverages the rear,” as Nic puts it. The car’s habit of understeering on entry and exit was now diminished enough to help him point the car where he wanted it more of the time.
In the past two years, he’s run the car largely in this configuration. He’s learned a lot about the car, and now feels it’s undersprung. The reason is that making the transition from brake release to the mid-corner/coast phase is hard to replicate. At least the 911 is willing to oversteer a little more now, though the problem is that it oversteers almost too readily.
He’s toyed with the handling somewhat by running a smaller tire. Downsizing from the aforementioned Apex wheels to a set of factory 17” 996 wheels measuring 17x7” and 17x9” wheels wearing 225 and 255-section Maxxis RC-1s, respectively. This tire change has made the car more neutral.
It’s a problem he aims to solve with stiffer, tailored coilovers in the near future. For now, he’s quite confident lapping this car—not only because he knows it, but because of its demonstrated reliability.
The M96 motor is a cause for concern due to the possibility of its IMS bearing failing and incurring a very costly rebuild. Nic went ahead and replaced the factory item with an LM Engineering replacement bearing, and was happy to report that the original single row bearing OE item looked fine after it was removed. “It really only happens in a 8% of MY 2001 and beyond engines—a small percent of engines I’ve heard and read about,” he added.
The only other engine modification he made was an FCD Brombacher extended sump, which adds another half quart of capacity to the motor and safeguards it from starvation when sticky tires are added. Beyond that, the 911 has been a vision of reliability. Aside from a water pump, nothing has failed.
“The car runs strong. The brakes haven’t given me a single problem, there’s good power available all the time, it never overheats, and it’s fairly easy on consumables.”
