Powerflex PFR5-415 Polyurethane Rear Lower Lateral Arm to Chassis Suspension Bush Kit (Pair) for BMW 1 Series E81 E82 E87 E88

Part Number: PFR5-415

Transform your BMW 1 Series rear end with Powerflex PFR5-415

Give your E8x chassis the precision it deserves. Powerflex PFR5-415 is a high-performance polyurethane bushing set designed for the inner mounting point of the rear lower link on BMW 1 Series E81, E82, E87 and E88. By replacing the tired factory rubber, this urethane upgrade tightens up the back axle, locks in geometry under load and delivers confidence-inspiring stability on fast road and track.

Why this upgrade works

• Superior control of toe and camber under acceleration and braking for a planted rear end
• Sharper turn-in, reduced rear steer feel and more predictable handling at speed
• Improved traction out of corners and more even tyre contact for better tyre life
• Durable polyurethane construction resists oil, road salt, heat and ageing far better than OE rubber
• Low NVH design keeps cabin refinement intact while boosting precision
• Backed by the Powerflex Lifetime Warranty

Fitment and position

For BMW 1 Series E81, E82, E87, E88. Fits the inner pivot of the rear lower control arm where it meets the body. Powerflex diagram location: 15.

What you get
