Powerflex PFF5-4650 Adjustable Polyurethane Engine Mount Bushes (Pack of 2) for BMW Z3 19942002 | Uprated Fast Road/Track Performance

Powerflex PFF5-4650 Polyurethane Engine Mount Bush Kit for BMW Z3 1994 to 2002

Give your BMW Z3 a tighter, more controlled feel with the Powerflex PFF5-4650 engine mounting bush kit. This adjustable polyurethane solution replaces tired rubber mounts to limit unnecessary engine movement, helping the chassis work properly, improving traction and making the car feel more connected on fast road and track use. We have installed these on customer Z3s and the results have been superb, with noticeably sharper response and stability while keeping cabin refinement very acceptable for daily driving.
