I'm hoping to join my first Cal Club / SCCA Autocross event at the April Fontana Test N Tune to enjoy some autocross. I have done autocross 4 times in my car with 3 different clubs, each time making improvements to myself and the car, but I have not done any SCCA events. I am undecided on Saturday or Sunday, but leaning toward Saturday assuming there will be more runs for more seat time.
My car is an LS-swapped '70 Nova with some modest suspension, brake & tire upgrades. I don't know how much it matters for Test N Tune, but is it safe to assume I'd be in the CAM-T class? Do you get many classic muscle cars at these Test N Tune events?
Any advice on which day i should attend? I'm there to have fun, learn more about my car and driving, watch other cars, and see how I can improve upon my time. I couldn't care less about placing, just as long as I have a safe and fun time. I'd like to avoid traffic if I can, because I do need to drive from Ventura County. I have a friend who might also be interested in joining for his 1st time autocrossing in his '67 Camaro.
I have an older Scorpion EXO helmet that is marked "M2005" at the back inside. Should I be concerned if I can't find a holographic label?
Here are some photos of my car from the last event I went to in Santa Maria w/ the Vapor Trail Vettes club.
