BMW F01 7 Series Poly Motor Mount Bush Inserts | PFF5-4020BLK

Upgrade the drivetrain feel of your BMW F01 7 Series with these Black Series polyurethane motor mount bush inserts. Engineered in a race-grade 95 Shore A compound, this insert set fills the voids in the factory engine mounts to control movement under load, delivering a tighter, more connected drive that enthusiasts and track-day drivers love.

We run these on our own builds and our customers consistently report crisper throttle response, cleaner upshifts and a more planted chassis during hard acceleration and braking.

Why choose these poly inserts

• Sharper pedal response for quicker acceleration
• More precise gear changes thanks to reduced drivetrain wind-up
• Stronger power delivery with less engine rock
• Improved balance on and off throttle in fast road and circuit use
• Helps prolong the life of the original rubber mounts by limiting excessive movement

Track-focused construction

• Black Series 95A polyurethane for maximum control of engine support geometry
• Intermediate solution between soft OE rubber and full solid or alloy mounts
• Inserts fit into the existing mount voids, typically installable without removing the mounts

Installation notes

A small increase in NVH, typically at idle, should be expected when stiffening the connection between engine and chassis. The firmer the compound, the more vibration will be transmitted.

Who this upgrade is for

Ideal for tuned and track-prepared F01 chassis seeking improved driveline stability, reduced engine movement and a more direct, performance-focused feel without switching to full replacement solid mounts.
