Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

These mounts are designed for the BMW E36 and E46 including the M3, Z3, and Z4 as well as the E90/E92 M3. Excluding the E46 XI. Revshift polyurethane motor mounts are made in the U.S.A. from high-grade polyurethane. Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevents the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws these mounts will hold your engine in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum end pieces. These mounts have removable screws for ease of installation. We recommend using Loctite on the threads during installation. Revshift Performance Engineering is a high-performance parts manufacturer with a focus on quality, reliability, and performance. Utilizing high-precision machining technologies and their very own Polyurethane Manufacturing Department, every Revshift product is designed, manufactured, and tested in-house at their Detroit, Michigan facility.

This is the rear rubber-isolated differential mount. The diff mounts take the bulk of the twisting and binding as power is transmitted through the differential. We use a Meyle HD rubber bushing for the rear mount as it's stronger than the factory part. (33176751808). We also recommend replacing the front differential mount 33171093175MY at the same time.

This Meyle replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it produces a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life.

This can also be used as an upgrade on the E30 M3. It has much more rubber in between the bolt holes which makes it last longer. This is 5mm thicker than the stock E30 flex disc so adjustment of the 2-piece driveshaft may be required. The original flex disc bolts can be re-used.

Applications:
1995-1999 E36 M3 manual & auto transmission
2001-2006 E46 M3, M3 CSL manual and SMG transmission
1991-1995 E34 M5 3.6 and 3.8 manual transmission
1998-2002 Z3 M Roadster, M Coupe - S52 and S54 engine manual & Auto transmission
2006-current E85 Z4 M Roadster, E86 M Coupe manual transmission
