Powerflex PFR5-420 Polyurethane Rear Subframe Front Mount Bushes/Bushings Kit for BMW 1 Series E81 E82 E87 E88 F20 F21 & 3 Series E90 E91 E92 E93 F30 F31 – Rear Axle Carrier/Cradle/Crossmember Mounts – Replaces 33316758259, 33316792509

Uprated rear axle carrier front mounts for BMW 1 Series and 3 Series

Unlock tighter chassis control and confidence-inspiring handling with this premium polyurethane bush set. Designed for the front positions of the rear axle carrier, this kit replaces tired factory rubber to cut unwanted movement, keep geometry stable and deliver crisp response on fast road and track day use. We fit these on customer cars at MJ Modifications and the results are consistently superb for daily driving and spirited runs alike.

Why this upgrade works

• Poly bush material resists flex compared with ageing OE rubber, giving a connected rear end feel
• Improves stability under acceleration and braking while helping tyres maintain consistent contact
• Enhances turn in and traction by limiting sub frame deflection under load
• Durable construction designed to outlast standard bushes in road and track environments

What you receive

2 x bushes for the front locations of the rear axle carrier. One pair services one vehicle.
