Powerflex PFR5-4025 Polyurethane Diff Front Mount Bush Kit - Rear Final Drive Front Hanger Mounts/Inserts - BMW 2 Series F87 M2, M2

Polyurethane Rear Final Drive Front Support Set - PFR5-4025

Upgrade the front supports for the rear differential on your F87 M2 with this premium polyurethane bushing kit from Powerflex. Part number PFR5-4025 replaces all four factory rubber mounts in the original front hanger, delivering tighter control of driveline movement for sharper, more predictable handling on fast road and track. Each bush is paired with an aluminium sleeve that features integrated support to further stabilise the final drive under load.

We have fitted this kit on customer cars and our own builds, and the feedback is consistently positive. Expect crisper chassis response, improved road holding and a more connected feel without the unwanted flex that comes with ageing OEM rubber.

Why choose these polyurethane mounts

• Reduces unwanted differential movement for more consistent traction and control
• Improves steering stability and cornering confidence by keeping geometry in check
• Enhances tyre contact with the road surface for grip you can feel
• Durable, correctly engineered polyurethane designed to manage NVH as well as or better than rubber
• Great long-term value with minimal maintenance
• Backed by a Lifetime Warranty from the manufacturer
