BMW Drivetrain Parts for BMW 3 Series E46 (1999-2005)

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.

  • Stainless steel & aluminum construction

The Dinan short shifter provides shorter shift throws with a crisper and more precise feel than a stock shifter. Instead of retrofitting a stock BMW lever, with all of its deficiencies, Dinan has engineered this billet aluminum shifting system. Special features engineered into this unit include a two piece fully isolated stick assembly, exclusive integrated and dampened pivot cup with self lubricating pivot ball, counter balanced to reduce effort and exclusive polymer "Iglide" T-500 lower pivot bushings that are impervious to contamination. Featuring an adjustable pivot, which allows this shifter to fit both standard and M Series applications. All of this combined with a simple straightforward installation provides a professional level shifter. Provides a 25% throw reduction in E36s, E39s and E46s and a 20% throw reduction in M3 and M5 applications.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty.

This is a 1-piece Chromoly conversion for the BMW E46 (6-Speed Manual Transmission ONLY, will not fit SMG). The shaft is 3" x .083" DOM tube with billet aluminum plates to convert the small bolt pattern on the factory transmission to use larger 1310 U-Joint and a 108mm CV to mount to the differential, which will eliminate any possible pinion angle issues. 

This shaft weighs 25 pounds and since there is no hanger bearing, it will make the car seem more athletic and give it a smoother power transfer. Unlike other aftermarket shafts for BMW's this shaft features a slider system that will let the shaft move in and out during racing and chassis flex. This shaft is now being balanced a new 9500RPM balancer to ensure a perfectly balanced shaft. Comes complete with precision machined front and rear conversion plates and all necessary hardware for installation.

The Driveshaft Shop has been manufacturing heavy duty replacement driveshafts for street and track vehicles around the world for the last thirty years. Every single shaft is dynamically balanced at over 9000 RPMs to ensure unbeatable reliability. With materials such as Carbon Fiber, Aluminum, and Chromoly The Driveshaft Shop has a solution for you no matter what the application.

This part fits the following BMWs:

The M Dynamic limited slip unit on the M3 is designed to be a pure street car differential. It's simply not up to the rigors of professional or amateur racing. The OS Giken Super Lock LSD is giant step up in from a stock M3 lsd unit. It's ready for the extreme conditions of racing, offers 100% progressive locking capability, and is able to do this while operating smoothly and quietly. It's use of advanced technologies that make it perfect for both street cars AND pro race cars... and everything in between. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've been using them in our own Championship winning M3 race cars.

OS Giken incorporated revolutionary new ideas when developing the their own limited slip diff, utilizing their accumulated racing knowledge and experience and over 4 years of development. Their design uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat. The end result of their efforts is the OS Giken's OS Super Lock LSD which offers incredible durability and reliability on street and track driven BMWs. The use of highest quality materials, precise machining, forged gears and sound engineering makes this LSD durable and reliable enough for road racing performance (which we can personally vouch for!). This is such a great design, in that it can be used in any situation -- whether it's for a street car, or a 100% Professional race car. Zero break-in required. Super smooth and quiet engagement, and 100% progressive locking capability. Professional installation is recommended.

This Limited Slip Differential Unit fits the following BMWs:
2001-2006 E46 M3 coupe & convertible
2008-2013 E9X M3 coupe & convertible
1991-1995 E34 M5 sedan
1999-2003 E39 M5 sedan
2006-2008 E85 Z4M Z4 M Coupe, Z4 M Roadster
