Powerflex Black Series Polyurethane Engine/Motor Mount Insert Bushings for BMW Z4 (E89) 2009-on | 95A Fast Road & Track | PFF5-4020BLK

BMW Z4 E89 Motor Mount Bush Inserts | PFF5-4020BLK

Unlock sharper response and a more planted driveline on your BMW Z4 E89 with this pair of Black Series polyurethane motor mount bush inserts. Engine movement under load robs you of precision. These high-durometer inserts target the voids in the factory rubber mounts to stabilise the powertrain for track-day confidence and fast-road control.

Built from 95A polyurethane, this upgrade sits neatly in the OEM mount cavities to limit flex without the cost and harshness of solid mounts or full replacements. In most cases they can be installed with the mounts still on the car, making this a smart, time-saving performance mod for 2009 onwards E89 owners.

• Crisper gear changes and a tighter, more connected driveline feel
• More immediate throttle reaction and cleaner power delivery
• Improved stability on and off throttle, especially in corner exits
• Helps extend the life of the factory rubber mounts by reducing excessive movement
• Ideal for tuned cars, spirited road use and circuit days

Our technicians have fitted these inserts to customer Z4s and the feedback is consistently positive. Expect a noticeable improvement in control and engagement. As with any uprated mounting solution, a small increase in cabin vibration at idle can be present, which is normal for a performance-focused insert of this hardness.
