As of right now I haven't taken it to the track to get any times. It isn't worth it if you go past half throttle and you just spin on the street...you know it isn't going to do that much better at the track. At 65 mph if you floor it, it just spins...kind of dangerous.
I think switching to the detroit locker instead of just spinning one wheel will obviously make a big difference. I have my Caltracs on the bottom hole so maybe I need to put it at the top as dennis112 mentioned. I am going to switch to the 6 cyclinder springs in the front before I do anything to do the rear leafs. But it does worry me that the rear suspension is that tight...should it be that tight, ideally?
Also, I forgot to metion this car is a C4 auto with no trans brake (will leave by footbraking to 3500 rpm).
