this is for ZIPPY02,you mention setting up the front suspension for equal pressure on the tires, How is this done,other than some long wheelie bars,back in the day we used to put an airbag in the rt.rear spring on open diff. rwd cars, can't do that on fwd cars, i have a 2004 MC SS L67,/a lot of mods even with nitto drag radials it will not hook,after the car was dynotuned my 60' times went from 2.0 to 2.2-2.4's how do you get a open diff car to launch as hard as a lsd car? any thoughts?
