The bush supplied is made using our Red 65A durometer material, which is approx. 15% stiffer than a rubber mount ensuring position, height and movement control. They are also offered in our 95A Black Series material for those wanting the ultimate in exhaust control for Track / Competition use.
To fit 1 to 4 Series models and Mini F56, we are also offering two new replacement mounts to swap out for the ageing original rubbers.
Unlike rubber mounts, our polyurethane will not deteriorate with age, and will not perish or break with weight making them the ideal accompaniment for your new exhaust system. Check out this short testing video.
