Yes replace the studs. dont want to re-do over a 30 dollar cheap out. Get some S50 cams (95 M3 OBDI only) and a chip and u should be good. Change RTABS too because they tend to wear out and u wont notice it until u drive in the rain. very very dangerous. I spun out my E36 off I75 because they were bad and made the rear end turn.
