Sharpen your BMW M rear end with a Powerflex differential nose mount upgrade

Swap out soft, ageing rubber for the Powerflex PFR5-4621 urethane bushing and gain rock solid driveline control on your E46 M3 or Z4 M Coupe and Roadster. By firming up the front of the final drive, this upgrade limits movement under load, giving you cleaner turn in, better traction out of corners and a more planted, confidence inspiring feel on fast road and track day driving.

We use this part on our own builds at MJ Modifications, and customer feedback has been superb. Expect a tighter rear end, reduced wheel hop and far less driveline shunt. Polyurethane resists oil, heat and wear far better than standard rubber for long term consistency, and the part is supported by a Powerflex lifetime guarantee for total peace of mind.
