X3 Differential Mounts and Upgrades

Rubber mounts are used to locate the differential to the subframe in RWD BMWs. This is one area that we like to focus on to improve power transfer, response time, and the overall feel of the drivetrain. By using a stiffer bushing you reduce or eliminate the 'wind up' and deflection of the stock rubber differential mounts when power is applied. A solid bushing will not twist when power (torque) is applied. Instead that power is directed to the drive wheels where it will do the most good. Our diff mount upgrades are solid rubber, Delrin, or aluminum kits depending on the application and the intended use. Even though these were developed for our race cars, we put them in a lot of street cars as well. The diff is not directly linked to the wheel and suspension so these are not as affected by bumps and road imperfections. Some additional drivetrain vibration may be felt through the chassis but in our experience it's very minimal. When installing one of our performance differentials make sure you also replace the mounts! And any subframe overhaul should also include solid diff mounts. There's no downside!
