Upgrade your BMW 1 Series rear differential mount with the Powerflex Poly Bushes Pack PFR5-425. This Rear Diff Front Mounting Bush kit is a proven performance upgrade for E81, E82, E87 and E88 chassis, delivering tighter driveline control, sharper handling and improved stability. Powerflex polyurethane bushes reduce unwanted movement in the rear differential front mount, helping to control torque reaction, minimise wheel hop and keep the differential located under load for better traction and more consistent power delivery.
Powerflex poly bushes are engineered to outperform ageing rubber bushes by controlling flex in the suspension and drivetrain. That means better chassis response, more precise alignment control and more tyre contact with the road. Correctly formulated polyurethane can be as good as, if not better than, rubber at suppressing noise, vibration and harshness, while offering significantly improved durability.

At Nforcd we have fitted these Powerflex rear diff front mount bushes to multiple E8x 1 Series builds. The feedback is consistent: crisper drivetrain feel, improved confidence on throttle and a noticeable improvement in rear-end stability without the soggy, worn-rubber vagueness.
If your 1 Series shows signs of imprecise handling, drivetrain thud, braking instability or uneven tyre wear, worn rubber bushes are a common cause. Replacing them with Powerflex polyurethane bushes is a cost-effective, long-term solution that restores control and boosts performance.
