Only my second time at a track. I went there thinking if I don't get into the 12's I would be bummed, and the best I got was a 13.3. I was told the track really sucks but I saw other cars hooking up. In second gear my wheels would spin when I got into the boost. How hard is it to install a 31 moser spline axle. Will I have to mess with the gears? I want to get some slicks to make up for my crappy driving. Having 4.10's does'nt help either. What kind of time should I have with about 360hp on street tires?
