yea to jet around in a 450hp viper was a blast. Got up to 130mph after turn 11 down the straightaway. But on turns, both of our cars can almost take it at the same speeds if taking the same lines.

As for the ball joints, don't turn them in all the way negative. You need them to be set to correct the negative camber when you lower the car. How come you got them? I thought that you are only lowering the car 1.5">?
Anyway, yes the spindle will rub/ hit the spring if adhjusted all the way negative.
