All the current and recent RWD GM cars and i suspect all trucks, the C5 to current Corvette , Camaro, pontiac gto, g8, the solstice and Sky, with the aluminum cast lower a arms, there aint much adjustment able to be done--its pretty tight. The camber is adjusted with cast aluminum cam bolts with a fixed washer head ----that fits into a notch,,, and each cam bolt is made differently to dial in / clock the lower front or rear a arm pivot in,
The uppers are fixed on all the modern cars.
My question is, are these gm cam bolts all standardized so they swap between all these vehicles?

Vstech?
