BMW E63 E64 M6 rear upper wishbone inner mounts PFR5-712H

Restore razor sharp rear axle control on your 6 Series M car with this Heritage Collection upgrade from Powerflex. Part number PFR5-712H replaces the inner pivot bushes on the rear upper wishbone, tightening up geometry, improving stability on throttle and braking, and giving you a cleaner, more confident turn in without spoiling the OE look.

We have installed these on customer E63 and E64 M6 builds and the transformation is immediate. The back end feels planted, alignment stays consistent under load and you get repeatable handling lap after lap and mile after mile. If your car still runs tired factory rubber, this is the smart refresh that makes the chassis feel younger and more precise.

Why it works

• Reduces unwanted flex at the inner joint of the rear top arm for truer camber and toe control
• Heritage finish blends with factory components while delivering modern performance
• Durable performance material outlasts ageing OEM rubber for long term consistency
• Great for fast road, spirited driving and restorations that want an OE style appearance
• Keeps the rear end composed over bumps and during hard cornering for better traction
