Powerflex PFR5-423 Polyurethane Rear Subframe Rear Mounting Insert Bush Kit (Pack of 2) for BMW 3 Series E90 E91 E92 E93 xDrive AWD 2005-2013 - OE 33316768645

Powerflex PFR5-423 Rear Axle Carrier Rear Mount Insert Bush Pair for BMW 3 Series xDrive AWD E90 E91 E92 E93 2005 to 2013

Transform the rear end of your BMW xDrive with this performance insert kit. Powerflex PFR5-423 replaces the soft factory subframe rear mount inserts with tough polyurethane for a tighter, more controlled chassis. Expect crisper steering, a more planted rear axle and confidence-inspiring stability on fast road driving without the usual increase in noise or harshness. It is a simple, effective upgrade that protects alignment and helps reduce uneven tyre wear on daily-driven and enthusiast cars alike.

• Sharper turn-in and predictable rear-end grip on all-wheel drive models
• Reduces subframe movement for improved braking composure and traction
• Helps maintain geometry under load for cleaner tyre contact and longer tyre life
• High-performance polyurethane resists oil, salt and heat far better than ageing rubber
• Insert-style solution for quick fitment and excellent NVH control
• Covered by the Powerflex Lifetime Warranty
