Powerflex Poly Bushes Pack – Rear Diff Front Mounting Bush – PFR5-4025 – BMW F80 M3 3 Series
Upgrade your BMW F80 M3 rear differential with the Powerflex PFR5-4025 poly bushes. This rear diff front mounting bush kit is a proven performance suspension upgrade for sharper handling, improved stability and more consistent traction on road and track. Powerflex polyurethane bushes control unwanted movement better than ageing rubber bushes, helping your tyres maintain maximum contact with the road for safer, faster, more predictable driving.
We have fitted and used these bushes ourselves, and our customers consistently report tighter rear-end control, reduced diff movement and a more connected feel without harshness. If you are searching for BMW F80 M3 rear diff bushes, BMW rear differential front mounting bushes, or a polyurethane suspension bush kit for the 3 Series M3, this PFR5-4025 kit is the go-to solution.
What this kit does
PFR5-4025 replaces all four bushes in the original rear diff front mounting bracket and includes aluminium sleeves with built-in support to increase control of rear differential movement. Correctly formulated Powerflex polyurethane offers excellent noise, vibration and harshness control comparable to, or better than, rubber while delivering significantly improved durability and performance.
