BMW Z4 M E85 E86 2006-2009 Polyurethane Final Drive Rear Mount Bushings | Part No. PFR5-4620

Transform the rear end of your Z4 M with this high-quality polyurethane bushing pair designed for the final drive rear mounting points. By replacing tired OE rubber with these precision-engineered urethane inserts, you tighten up rear axle location, reduce drivetrain shuffle, cut wheel hop and enjoy cleaner power delivery on fast road and track. The result is a more planted, predictable BMW that puts torque down with confidence and improves steering feel and braking stability.

We have installed this set on customer E85 and E86 M Coupe and M Roadster models and the feedback is consistently excellent: sharper response, reduced slop around the diff, better traction out of bends and a more connected drive without harshness.
