BMW Drivetrain Parts for BMW 1 Series

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.

  • 30% shorter shifts
  • Counterbalanced for great shift feel
  • Stainless steel & aluminum construction
  • Rubber isolated for reduced NVH
  • Maintains stock shift feel with uprated stock-type bushings

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 30% throw reduction in E82 128i/135i, E9X 325i/328i/330i/335i, and E60 530i/545i/550i.

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.

Everyone knows that heat is the enemy of your automatic transmission. And everyone knows that higher power levels generate more transmission fluid heat. Now you can extend the life of your automatic transmission by installing the new Burger Motorsports High Capacity Trans Cooler kit. This unique plug-and-play kit replaces your factory coolant to trans fluid heat exchanger with a high-capacity fender-mounted air-to-trans fluid radiator. Includes all mounting hardware, lines, and coolant caps required for installation. Installs inside the driverside fender providing ample airflow over the large cooling core via existing openings. The result is dramatically reduced transmission temperature and extended transmission life. This kit is strongly suggested for any BMW E chassis automatic running larger than factory turbos. FEATURES AND BENEFITS Dissipates excess transmission fluid heat Reduces transmission fluid temperature Increases transmission life when racing Increases transmission oil capacity Fitment: 2008-2013 E81 E82 E87 Coupe and Hatchback 135i 2008-2013 E88 Convertible 135i Compatible with both RHD and LHD vehicles. Not compatible with manual transmissions.

The thermostat maintains the oil exiting the transmission at the rated minimum temperature in most conditions. Without a thermostat, the transmission fluid coolers are likely to over-cool the fluid, delaying transmission warm-up and performing the critical function of bypassing the cooler until the oil has reached its minimum operating temperature.

As Used on Project E92 335i
A turbocharged BMW such as the 135i or 335i needs traction to put that power to the ground. The stock differential of both the 135i and 335i only put power to one wheel -- this just won't cut it! Upgrading to a limited slip differential means power to BOTH wheels, for better launch, acceleration, grip, and track handling. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've used their products on our own Championship winning E46 and E92 race cars.

OS Giken's newest innovation is their quietest and smoothest limited slip unit yet - the Traction Control Differential (TCD). TCD is similar to their excellent Superlock differentials but with additional oil channels and pathways. The added lubrication makes diff operation smoother and quieter than before (not that there were many complaints to begin with). The locking engagement is more progressive than before which makes this diff more suitable for street driving. Track cars and drift cars should still use the Superlock LSD as it will transition to lock sooner. TCD is an evolution of a diff that was already extremely well-engineered for road and track use. Not willing to rest on their laurels, they took their superior engineering a step further.

With the 135i/335i LSD unit, they have incorporated revolutionary ideas into the overall limited-slip design which uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat. 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!). Zero break-in required. 100% progressive locking capability. 

Installation note: BMW differentials use many unique and BMW-only parts and components. Only technicians who are experienced and familiar with BMW parts should perform the installation. The OS Giken LSD is the limited slip unit (or 'chunk') only. It replaces the stock non-LSD chunk but the original ring and pinion and other internals must be installed with the OS Giken unit. This unit will only work on 335i manual differentials with a bolt-in or modified ring gear. Proper setup and spacing is critical for long life operation. Incorrect installation will void the warranty. We also offer the TCD unit pre-installed -  see our performance diff catalog for more info.

The OS Giken TCD Diff unit fits the following BMWs:
2008-2012  E82 BMW   135i with manual transmission
2007-2011  E90 BMW   335i - Sedan with manual transmission
2007-2013  E92 BMW   335i 335is - Coupe with manual transmission
2007-2013  E93 BMW   335i - Convertible with manual transmission
