Black Series option for Track and Motorsport

For maximum control of chassis geometry and dedicated track use, Powerflex Black Series bushes use a stiffer Black 95 Shore A compound. They are designed for the track and engineered for racing where the highest stiffness and response are required. Expect a greater increase in NVH compared to the Yellow 70A road inserts.

Fitment and installation

The PFF5-4020 engine mount insert kit is designed to fit into the voiding of the OE BMW Z4 E89 mounts and can be installed without removing the mounts from the vehicle. A small increase in Noise, Vibration and Harshness at idle should be expected when stiffening the mount that connects the engine to the chassis. The harder the compound, the greater the NVH.
