i agree with mustang5l5 with about needing quads after control arms
i installed a set of control arms, upper and lower and didnt have quads on for a week or so. the car wheel hopped bad, i ordered the gabriel set from autozone, 2 for 50 bucks i run them flipped around, it clears both my steet and track tire combos so why not run them. it cured my wheel hop and i couldnt be happier.
and yes they are called steering dampeners, i have no idea why. but they are.
