The SuperPro alloy lower control arm and radius arm kit for the 2008 BMW 128i is a performance-oriented replacement that reduces arm movement and adds adjustability. The set includes SuperPro bushings and ball joints, delivers about 1° extra camber and provides on-car adjustable radius arms with up to 0.8° caster change—useful for correcting a pull or increasing directional stability while preserving articulation without added noise.
