BMW E30 E36 ADJUSTABLE ALUMINUM LOLLIPOPS Adjustable front control arm bushings - BMW E30 / E36 Upgrade your front suspension with our adjustable control arm bushings, designed for precise settings and improved wheel geometry. Perfect for both track and drift builds. Advantages: Adjustable caster (KWSZ) - provides optimal wheel angle and better steering response, especially when drifting. Moveable wheel position in the wheel housing - ideal for conversions on E30 where the wheel otherwise ends up too far back. Low weight and high strength - the housing is made of aluminum, which reduces the weight by about 1 kg compared to the original.
