I am not sure there are many rules in stock at socal. I think 13.5 and lipo are allowed in that class. If you are running a 10.5 lipo then I would run with mod. That should be plenty of power to compete. They are racing fri and Sunday. Turnout has been about 4 heats total for each. Usually a novice class, stock buggy, stock truck and mod buggy if I am not mistaken. I have not been there in about a month but that seemed to be what it has been like for the last 6 months or so?
