Polyurethane Motor Mount Inserts for BMW G11 7 Series 2015+ | Part No. PFF5-4020BLK

Unlock sharper responses and tighter drivetrain control on your BMW G11 with this race-focused pair of polyurethane mount inserts. Designed to support the factory mounting bushes by filling the voids, PFF5-4020BLK limits powertrain rock under load for more precise throttle feel, cleaner upshifts and improved power delivery on spirited drives and track days.

Made from a tough 95 Shore A Black Series compound, this upgrade gives you a serious stability boost without the cost and harshness of solid metal mounts. The clever in-situ design means these inserts can be installed without removing the original mounts, making it a smart, efficient performance enhancement for tuned builds.

Why enthusiasts choose PFF5-4020BLK

• Firmer motor support for crisper throttle response and reduced driveline shunt
• More positive gear change feel under acceleration and braking
• Better torque transfer for consistent traction and chassis balance
• Helps extend the service life of the standard rubber mounts
• Quick fitment in situ, no press or mount removal required

Track-focused Black Series performance

Engineered for circuit and motorsport use, the Black Series compound maximises control of mounting geometry for serious drivers demanding predictable handling and repeatable lap-after-lap performance.
