These solid UHMW mounts have been designed with one thing in mind… To increase on-track performance by lowering the center of gravity in your BMW. Our mounts will lower the engine by a full 5mm. This moves the weight down low in the chassis, dramatically improving handling and grip. Our UHMW mounts are legal for the NASA Spec E46 racing class. Our solid UHMW enginemounts will keep everything in place, dramatically changing the responsiveness of your race car. We highly recommend installing the transmission and engine mounts as a complete kit.
