BMW F87 F80 F82 F83 Motor Mount Insert Upgrade - Powerflex PFF5-4021BLK 95 Shore A Polyurethane
Give your F-series M car the razor-sharp response it deserves. This precision-moulded 95 Shore A polyurethane motor mount insert set from Powerflex minimises unwanted engine and gearbox movement, delivering cleaner power delivery, snappier upshifts and a more connected feel under load. Perfect for fast road, track day and spirited driving, it is a robust, bolt-in enhancement for the F87 M2, F80 M3 and F82 F83 M4 platform.
We use this kit on our own builds at MJ Modifications and on customer cars. Feedback is consistently excellent: crisper shift action, reduced driveline lash, steadier throttle transitions and more confidence when pushing hard. If you want a fit-and-forget solution that tightens the drivetrain without replacing the entire OE mount, this is the one to choose.
Key advantages
- High-stability 95A polyurethane insert controls engine rock for improved traction and response
- Fills the open voids in the factory rubber mounts to limit fore-aft movement under acceleration and braking
- Enhanced shift precision and consistency for both manual and dual-clutch transmissions
- More direct power transfer and a planted, predictable chassis on corner entry and exit
- Helps reduce wheel hop and driveline shunt on hard launches and aggressive downshifts
- Durable, oil-resistant material designed for repeated heat cycles and track abuse
- Smart insert design - typically installs without pressing out the original mount
Ideal use cases
Street performance, fast road, track days, sprint events, time attack and drivers seeking sharper pedal response and repeatable shift feel from their F8X or F87 M car.
