Powerflex Black Series PFR5-720BLK Polyurethane Rear Subframe/

Uprated rear axle carrier front mount bushings for BMW E60 E61 E63 E64

Transform the way your 5 Series or 6 Series drives with this motorsport-grade rear cradle front mount bushing set. Built from the Powerflex Black range using a 95A durometer compound, these bushes lock down the rear axle carrier to keep geometry stable under hard braking and cornering. Expect a tighter, more predictable rear end, crisper turn-in and confidence on fast road, track day and competition use.

If you are chasing a precise, connected feel from the back of your BMW, this is the go-to upgrade that replaces the soft factory rubber with a performance alternative that resists deflection and keeps alignment true when loaded.

Why this upgrade
