Powerflex PFR5-413 Rear Upper Lateral Arm to Chassis Suspension Poly Bushes Kit for BMW 1 Series E81 E82 E87 E88 (2 Bushes)

Sharpen your BMW 1 Series rear-end response with uprated polyurethane bushes

Transform the way your E8x handles with this premium polyurethane bushing kit for the rear upper link inner mounting point to the body. Engineered to replace ageing rubber, these uprated bushes keep the rear geometry locked in under load, delivering crisper turn-in, better traction out of bends and rock-solid braking stability. If you want a more planted, confidence-inspiring BMW 1 Series that feels precise on B-roads and composed on track, this is the upgrade.

Part number: PFR5-413

Real-world results

We run these bushes on our own builds and customer cars and the feedback is consistent: firmer rear-end support, cleaner turn-in, reduced squirm under hard braking and more confidence when pushing on. Customers regularly report a more connected feel and tidier tyre wear after fitting PFR5-413.

Installation and alignment

Direct swap for the OE rubber component at the rear upper camber arm to body position. Professional fitting is recommended. A four-wheel alignment after installation is strongly advised to maximise performance and tyre life.
