Poly Motor Mount Void Inserts for BMW F07 5 Series Gran Turismo | Part No. PFF5-4020BLK

Unlock cleaner power delivery and crisper shifts on your BMW F07 5 Series GT with these Black Series polyurethane motor mount void inserts. Engineered to nest into the cavities of the factory mounts, they limit drivetrain twist for a more connected feel on fast road and circuit use. We run these on our own builds and customer feedback has been excellent, praising the improved response and precision.

Why choose these uprated mount inserts

• Quicker throttle response and stronger power transfer under load
• More positive gear changes with reduced driveline slop
• More stable on and off throttle balance through corners
• Supports the life of the original rubber mounts by controlling excess movement
• Install-friendly design that fits into the OE mounts without removing them from the car

Track focused Black Series compound

Manufactured in the Black 95 Shore A polyurethane compound for maximum control of drivetrain geometry. Ideal for tuned cars, track days and motorsport where precision and consistency matter.

Installation notes

These inserts push into the voids of the standard mounts to curb movement. A small increase in cabin vibration at idle is normal when stiffening the link between engine and chassis. The firmer the compound, the more NVH you may notice.
