Powerflex PFR5-4025 Rear Diff Front Mount Bush/Bushing Kit (4) for BMW M3 F80 - Polyurethane Urethane Differential Carrier Mounts - Final Drive Front Bushes - Fits OE 33172284774 - BMW 3 Series F80 Rear Axle Diff Mount Upgrade

PFR5-4025 Rear Diff Front Mount Bushings Kit for BMW M3 F80

Transform the way your F80 drives with the PFR5-4025 polyurethane front mounts for the rear differential. This 4-piece upgrade locks down the final drive more effectively than tired factory rubber, sharpening response and keeping the rear axle planted under acceleration, cornering and braking. Expect a tighter, more composed M3 with crisper turn in, improved traction and far less unwanted movement from the drivetrain.

We run these bushes on our own cars and have installed them for many customers. The feedback is consistent. Reduced diff shunt, less wheel hop, more stability and a more connected feel without an increase in harshness. If you are chasing precise geometry control on road or track, this kit delivers.
