Powerflex Track Front Wishbone Rear Bushes (E46 Hybrid) - Z3 (1994 - 2002) - PFF5-3601BLK

BMW Z3 1994 to 2002 Control Arm Rear Mount Poly Bush Upgrade – PFF5-3601BLK

Unlock sharper turn-in, stable geometry under load and long-lasting performance with these motorsport-grade polyurethane control arm rear mount bushes for the BMW Z3. Part number PFF5-3601BLK uses a split design in firm 95A Black material to deliver precise steering feel and repeatable alignment on fast road and circuit use.

This clever hybrid layout features a hexagonal inner to suit the E46 aluminium lower arm and an outer sized to the E30 or E36 style lollipop housing used on the Z3. The result is smooth articulation with minimal binding, excellent durability compared to rubber, and a direct, confidence-inspiring front end.

Why choose this suspension upgrade

• Improved steering response and braking stability
• Consistent caster and toe under hard cornering
• Free-moving split bush design helps reduce stiction
• Hard-wearing 95A Black polyurethane resists oil, heat and ageing
• Ideal for track days and fast road driving
