Powerflex PFR5-1927 Poly Insert Kit for BMW F30, F31, F34 Rear Diff Front Mount

Unlock sharper rear-end control and cleaner power delivery with the Powerflex PFR5-1927 insert set. This pair of polyurethane inserts sits inside the factory front mount of the rear final drive to curb excess movement, giving your BMW 3 Series a more connected feel, improved traction out of bends and a more predictable response when you get on the throttle.

We run this upgrade on our own builds and it is a customer favourite for good reason. Expect a tighter drivetrain, less slop under load and confidence-inspiring stability without compromising day-to-day usability. A high-impact handling mod that offers serious value.
