Autocross Competition Event

Welcome to the registration page for our October 2020 autocross hosted by North Bay Corvette Association in association with Trinity Touring Club, and our friends at Santa Clara Corvettes.  NBCA was established in 1967 and has been offering a variety of activities including competition events for Corvette owners and other Sports car enthusiasts in Northern California.  Non-Corvettes are quite welcome at our autocross events.  While this is a Western States Corvette Council (WSCC) and Trinity Touring Club points competition, all cars are included in the results and get ranked in top time of day results.  You can see how you did against all drivers and cars.

We operate clean, well organized events, and have for 50 years. Come play with us.


We give 5 runs to each entrant.  You are welcome to register for two run groups each day for twice the fun.  Also on Saturdays, we usually have fun runs after the last run group, charging 2 runs for $10 (Please bring cash for fun runs!)

Come out and join us for some good old Nord Fjord fun.

* Motorhomes / camping trailers may stay overnight at Thunderhill Raceway (Thunderhill charges a fee).  You pay this fee to NBCA - and we pay Thunderhill. Note- You get locked in when their guard closes the gate for the night, so be prepared. 

We will have real-time scoring. As soon as a score is recorded in our scoring computer, the run times will be available for viewing. (Unless we lose our WIFI connection) A link to the scoring results will be available at
