About this event
We're running on the 3-mile, traditional Thunderhill course. Thunderhill Raceway Park is a fast, technical driver’s track with an excellent surface, plenty of run-off, and outstanding amenities, including covered paddock space, plenty of electric power in the paddock, a comfortable lounge with WiFi, and an enclosed third-floor Tower Viewing Area with elevator service.
All CSRG eligible cars are welcome along with Larry Oka Racing Series-1 Miata Group. We invite Sports 2000 cars through the 80s to come try vintage racing.
Thunderhill is a sound-control track, with a maximum of 103db sound allowed, so fit mufflers if in doubt.
Willows is a historically significant agricultural town and County Seat, with some interesting architecture and good quality overnight accommodations in a wide price range. While there is perhaps a shortage of four-star restaurants, there are some good eateries within fifteen miles of town, and the CSRG Saturday dinner catered by Jim Thompson is always very good. Some 40 minutes away is the quite sophisticated University Town of Chico, which has great shopping and food.
Fees: CSRG requires all drivers be either a Full Racing Member of CSRG, or a Single-event Member. Our friends from other racing organizations may choose the Single-event Membership for $75, but we encourage you to consider joining CSRG as a Full Racing Member ($150/yr) and enjoy the full benefits of membership throughout the year. Full Racing Members of CSRG who haven't renewed their membership must renew at <csrg.motorsportsreg.com> before their race entry is processed.
