are runnng the chevy and toyota shackels (doubled up) on the rear? if you have the spring holders cut to where the rear pack comes apart, when breaking, the rear pack will unload and come up into the air causing it to nose dive. also, i have procomps all the way around on mine and had really bad body roll with 63 rear and NWOR rears up front. changed out to 5125's up front and procomps gas charged for the rear and it fixed the problem.
