BMW E90 E91 E92 E93 xDrive rear subframe rear mounting insert bush kit PFR5-423

Powerflex PFR5-423 replaces the rubber rear subframe rear mounting inserts on E90/E91/E92/E93 xDrive models - all petrol and diesel variants, including the E91 Touring. Not for non-Touring petrol-only cars (use PFR5-421 instead).

These polyurethane inserts eliminate subframe flex, sharpen turn-in, improve braking stability and reduce uneven tyre wear. A genuine fast-road or track-day upgrade - no OE replacement framing, no fitting questions, just precision-engineered parts that bolt straight in.

• Pack of 2, position: rear subframe rear mounting insert (Diagram ref: 20)
• OE cross-reference: 33316768645
• Lifetime warranty from Powerflex
• Resists oil, road salt and heat far better than rubber
