Uprated Poly Motor Mount Insert Kit - Black 95A - PFF5-4020BLK
Unlock sharper response and rock-solid drivetrain control with this Black Series poly insert kit. Built from a high-stiffness 95A compound, these inserts occupy the cavities in the factory rubber mounts to curb unwanted movement under load. Ideal for tuned cars and track day use, delivering more precise power delivery and a crisper gearshift feel without the cost or harshness of full solid mounts.
Why enthusiasts choose this upgrade
- Firmer launch and cleaner upshifts for a more connected drive
- Reduces drivetrain lash for improved throttle modulation
- Enhances stability on and off throttle for better balance through corners
- Helps prolong the life of original rubber mounts by limiting deflection
- Quick install design - fits into the OE mount voids without removing the mounts
We have fitted these inserts on customer cars and the feedback is consistently positive - tighter drivetrain control, slicker shift quality and a more direct feel when getting back on the power.

What to expect
Stiffening the link between engine and chassis increases control, so a slight rise in cabin vibration at idle is normal. The trade-off is significantly improved precision where it matters.
Perfect for
- Performance builds seeking a stronger motor mount solution without going full solid
- Drivers chasing better shift feel and torque management
- Track day and fast road use where engine movement reduction is a priority
