Collapsing and worn engine mounts can mean big trouble for N52/N54/N55 cars. The stock mounts are filled with fluid that can leak or evaporate over time. That leaves the mount unstable and too flexible to properly support the engine. The side effects of a worn engine mount are: shaking and vibrating engine, driveline twist from engine torque that can break or snap bushings, and broken motor mount arms and bolts. If you're tired of replacing engine mounts you'll be very pleased wtih these solid rubber versions.
Not only are these more reliable than stock fluid-filled mounts, they are slightly stiffer than new stock mounts thanks to a solid rubber construction (no voids in the rubber) but designed for street use so they remain quiet and comfortable. The solid rubber has less deflection than a stock mount, so no wasted engine and transmission motion. Less wasted motion gives you more torque to the wheels (it's not spent twisting the engine) and better shifts.
Sold as a set of matching engine and transmission mounts.

Your rear differential is indirectly connected to your right foot through the engine and driveline, and connected to the seat of your pants through the chassis. Soft factory rubber differential bushings absorb vibrations between chassis and differential, providing comfort and softness in both of these connections.
Enter ECS Tuning's In-House Engineered Performance Polyurethane Differential Bushings. By eliminating the deflection factory rubber bushings permit, the connection between your right foot (and your seat) to the wheels is improved. Removal of this slop allows for crisper power transfer from differential to wheels, which means better throttle control while carving a canyon road, drag racing, sliding the rear end out, or just driving to work. This is achieved without the harshness or vibration associated with delrin or solid differential mounts.
Featuring a tough 88A durometer polyurethane and Black anodized 6061-T6 aluminum Sleeve, our Performance Polyurethane Differential Bushings are more resistant to chemicals, ozone degradation, road salt, and general wear and tear than factory rubber bushings, resulting in a longer service life.
Drive line slop is often caused by faulty engine and transmission mounts. This can result in knocking noises under heavy acceleration, excessive vibration, and a less responsive feel in power. These Genuine BMW mounts are perfect to eliminate these problems and provide long lasting reliability.

Genuine BMW Engine Mount (left & right) Genuine BMW Transmission Mount (x2) Genuine BMW Installation Hardware (x6 bolts, x6 nuts)
