Powerflex Rear Diff Front Mounting Bush - G80 M3 (2020 on) - PFR5-4024

Rear differential front mount upgrade for BMW M3 G80 — PFR5-4024

Unlock sharper traction, stronger launches and a tighter rear end with this complete polyurethane front mounting solution for the rear differential on the BMW M3 G80, 2020 onwards. This is a full bush replacement that swaps out the factory rubber for a performance-focused setup designed to control driveline movement and help curb wheel hop and axle tramp under hard acceleration.

Engineered from 80A Shore purple polyurethane working with CNC machined 2011-T6 aluminium hardware that is finished in black anodising, this kit delivers long-term durability and precise alignment of the diff under load. Expect more consistent power delivery off the line and improved stability on fast road and track day use without the soggy feel of tired OE mounts.
