SPEEDSF CHALLENGE - DECEMBER 15, 2019 - ROUND 15 @ THUNDERHILL RACEWAY
Well, THIS was certainly an EVENTFUL SpeedSF Challenge - a truncated session, crazy field expeditions, and major talking points to close out 2019’s SpeedSF Challenge at Thunderhill on the Bypass configuration. If it wasn’t recorded on video, did it really happen? 27 fast, faster, and fastest bois participated as evidenced by broken lap records across 3 classes. If you were there, you knew what went down. It wouldn’t have been an end-of-year Challenge session without the craziness for sure.

SPEEDSF CHALLENGE - DECEMBER 14, 2019 - ROUND 14 @ THUNDERHILL RACEWAY
We start off Day 1 of the Thunderhill SpeedSF Challenge doubleheader featuring the Cyclone configuration and broken Challenge lap records across four classes! It’s been quite a while since we’ve run the Cyclone config, but it was a great way to start the weekend! With 19 drivers participating for the final Challenge weekend of the year, is there really a better sendoff?

SPEEDSF CHALLENGE - NOVEMBER 29, 2019 - ROUND 13 @ BUTTONWILLOW RACEWAY
Ah, Black Friday. There are those that get up early in the morning to blow away their money on frivolous retail deals while jumping over each other and causing general chaos, and then there are those who get up early in the morning to blow away their money on gas, consumables, try outdo each other on a race track and cause controlled chaos. The latter sounds a bit more attractive.
What else is there to do after Thanksgiving other than to join the SpeedSF Challenge at Buttonwillow Raceway for the annual Black Friday event? 21 drivers certainly thought it was a good idea to join the party! With 3 new broken records, it certainly made for an entertaining post-holiday event!

SPEEDSF CHALLENGE - NOVEMBER 10, 2019 - ROUND 12 @ SONOMA RACEWAY
Fast boi club right here. Featuring a race car, a non-production-based race car, and then another race car, it was down to pure power and finesse, squeezing everything out of each drivers’ respective chassis. 3rd place finisher who ALMOST got into 2nd place, David Colbert, piloted his 1980 Lola T540 D Sports Racer around Sonoma Raceway and put down a 1:43.123 lap time, while Mark Hamilton Peters whose 1:43.104 lap time answer in the GT4 Mustang earned him 2nd place on the podium. In 1st place was the winner by a landslide and record-breaker for the SpeedSF Class X lap record at Sonoma Raceway - Ben Sloss. His Ferrari 488 GT3 lit up the track with his blistering 1:35.044 lap time. Dashing!


SPEEDSF CHALLENGE - SEPTEMBER 22, 2019 - ROUND 10 @ THUNDERHILL RACEWAY - WEST
Bunch of fools in this group - Three drivers, three podium-placers! Andrie Hartanto drove some type of vehicle to take home 1st place! Andrie and the invisimobile drove levitated or something around Thunderhill West and used its magic powers to get a 01:20.795. This was obviously more of the car than the driver so let’s just take this with a grain of salt. A REAL driver by the name of Gary Yeung, piloted his Dirty Mango S2000, taking home 2nd place thanks to his 01:20.795, just a hair slower than the 1st place guy in the Mystery Machine. 3rd place finisher Gary Wong took a wrong-wheel drive Honda around the circuit for a 01:23.042 lap time. Probably faster than his Dirty Coconut S2000, tbh.




SPEEDSF CHALLENGE - JUNE 16, 2019 - ROUND 6 @ WEATHERTECH RACEWAY LAGUNA SECA
This was a great day out for all of our drivers. The S2000’s dominance was displayed once again in classes S2-S4 with Gary Y, Gary W, and Sohan “Gary X” Kota respectively leading the way in showing the S2000 prowess.
Excellent job to our who won their places and THANK YOU to everyone who participated in the SpeedSF Challenge! For those who are still chasing podium finishes, more seat time, coaching, and watching videos of the track will certainly get you there!

SPEEDSF CHALLENGE - MAY 31, 2019 - ROUND 5 @ THUNDERHILL RACEWAY 5-MILE!
With class-setting lap times thrown down for Groups S1-S4 + Group X, it’ll be interesting to see what August 30th’s 5-mile Challenge will result in. S5 is certainly ripe for the pickings, as the 2014 class record set by Eric Lin in July 2014 stands at a 03:55.190. Someone PLEASE break that record!
