PFR5-4616 Polyurethane Rear Wishbone Inner Mounts for BMW Z4 M E85 and E86 2006 to 2009

Sharpen your Z4 M’s rear axle with this premium polyurethane bushing set from Powerflex. Part number PFR5-4616 replaces the soft factory rubber at the inner pivot of the rear lower arm, tightening up chassis control for a more connected, confidence-inspiring drive. Ideal for spirited road use and track days, these bushes help the car hold alignment under load, delivering cleaner traction and better balance through fast corners.

Why upgrade to these polyurethane mounts?

• Crisper rear-end response with reduced deflection under braking and acceleration
• Improved camber and toe stability for consistent geometry and tyre contact
• More grip and traction on uneven surfaces without harshness
• Long-lasting, maintenance-free bushings designed to outperform ageing rubber
• Excellent NVH control from Powerflex’s proven polyurethane formulation
• Backed by the Powerflex Lifetime Warranty

Direct-fit inner pivot bushes for the rear lower arm on the following models:

• BMW Z4 M Roadster E85 2006 to 2009
• BMW Z4 M Coupé E86 2006 to 2009

Real-world gains

We have installed PFR5-4616 on customer Z4 M builds and our own cars. Drivers consistently report tighter rear stability, cleaner turn-in and a more planted feel on B-roads and at track days, with no unwanted noise or vibration.
