BMW Z4 E89 rear subframe front bush kit - Powerflex PFR5-4610

Powerflex PFR5-4610 replaces the two front rubber bushes on the E89 Z4’s rear subframe with precision-moulded polyurethane. Firmer than OEM, they reduce deflection under load - sharpening turn-in, tightening rear axle response and improving traction on exit.

Not a full track-spec setup, but a proven fast road or occasional track day upgrade. Minimal NVH increase over stock; no geometry changes or modifications required.

• Pack of 2 - correct count for E89 rear subframe front position
• Lifetime warranty from Powerflex
• Direct fit - reuses original hardware
