BMW E90 E91 E92 E93 xDrive rear upper control arm to hub bushes (PFR5-412)

Powerflex PFR5-412 polyurethane bushes replace the rubber units where the rear upper control arm meets the hub on E90, E91, E92 and E93 xDrive models. They’re a fast-road or track-day upgrade that sharpens rear-end response and holds camber more consistently under load.

• Stiffer than OEM rubber but tuned to avoid excessive NVH
• Resist oil, heat and ageing far better than factory rubber
