Hey, I just got a 12L3 and need some basic setup to start out. I have raced touring for years and now that we are going to have a close indoor track I figured I would try it out. We ae going to be running 4 cell stock and I will most likely run a GM3. What would be a good starting point for gearing??? I have heard that Purple fronts and White or Gray rears is a good starting point. Also what front springs, etc?
