PowerFlex BMW E36 / E30 / Z3 / Z1 Front Lower Control Arm Rear Bushing - Aluminum Shell (Offset)

PFF5-5303 includes a CNC-machined aluminum outer shell with an eccentric bore, increasing caster by 6.5mm / 0.5deg (standard '96-'99 M3 geometry). With the machined shell, and reducing the amount of polyurethane material used, we have increased stiffness by a further 50% over PFF5-301 and PFF5-303, and a massive 250% over the standard OE rubber bushing. The results are incredible, with minimal deflection under steering load and braking, while maintaining a balance of compliance and performance.
