Recently finished my Ls1 swap in my 1988 Monte Carlo and under wide open throttle it’s either axle hopping or trying to throw the driveshaft out of it. Car is lowered 4” in front and 3” in rear so wondering if pinion angle has been affected and the car also still has stock control arms with stock bushings in them which I’m sure isn’t helping. Wondering what would be my best course of action to fix this? Aftermarket rear control arms with adjustable uppers to get the pinion angle dialed in? If so what’re you guys running
