Powerflex BMW E46 3 Series & M3 Rear Shock Absorber/Strut Top Mount Bracket with Polyurethane Bush Kit (10mm Pin) - Rear Upper Damper Mount RSM Upgrade - PFR5-5630-10

BMW E46 and E46 M3 Rear Upper Shock Mount Kit with Poly Bushings, 10 mm Pin, PFR5-5630-10

Unlock sharper handling and rock-solid rear axle control on your E46 with this uprated rear upper strut mount bracket and polyurethane bush set. Built by Powerflex for drivers who want clean steering feedback, improved stability and dependable longevity, this kit replaces soft, ageing rubber with performance poly bushes that keep the damper located precisely under cornering and braking loads.

We run this exact setup on our own E46 builds and many customer cars. The result is a more connected chassis, better traction out of bends and reassuring stability at speed. Expect a noticeable improvement on fast road and track while maintaining excellent ride quality and low NVH when installed correctly. Backed by the Powerflex lifetime warranty for peace of mind.
