Find Parts That Fit Your Vehicle

BMW Drivetrain Parts

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.

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. 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. 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.

For G-Chassis BMW & A90/A91 Toyota Supra High torque loads, hard launches, and aggressive driving expose the factory differential mounting’s built-in compliance. Under power, the differential can shift excessively, resulting in wheel hop, inconsistent traction, and increased stress on drivetrain components—issues that become more pronounced on tuned or track-driven cars. The BMS Differential Support Bracket Brace corrects this weakness by reinforcing the differential mounting point and securely tying it to the subframe. By controlling unwanted movement, the brace improves rear-end stability and ensures power is transferred to the ground more efficiently. Why Upgrade? OEM differential mounts favor NVH reduction over control. As torque output increases, that compliance translates into drivetrain shock and lost traction. This brace stiffens the system where it matters most, reducing flex and improving load management under acceleration. Performance Benefits Improved launch consistency Significant reduction in wheel hop Increased rear-end stability under load More precise and predictable power delivery Engineered for Demanding Use Designed around factory mounting points, the BMS Differential Support Bracket delivers precise OE-level fitment with increased structural rigidity. Its robust construction resists deflection under high torque, while upgraded hardware provides greater clamping force for long-term reliability. Fully bolt-on for straightforward installation on both stock and modified vehicles. Key Features Reinforces rear differential mounting Limits differential movement under load Enhances traction and drivetrain response Heavy-duty construction for high-performance applications Bolt-on installation using factory locations Compatible with G-chassis BMW and A90/A91 Supra A focused drivetrain upgrade for drivers who demand consistency, control, and durability at higher performance levels.

Single mass flywheels can be resurfaced while it is recommended that dual mass flywheels are not.
Dual mass flywheels contain a rubber damper that will wear out, single mass flywheels do not have this and are inherently easier to maintain
Single mass flywheels also provide more consistent clutch feel when compared to the dual mass "self-adjusting" clutch that is notorious for inconsistency.
Valeo's single mass flywheel conversion is designed to be a similar weight and mass to OEM, making it an ideal choice for a daily driver

Valeo Dual Mass Flywheel Conversion Kit for MINI Cooper S/JCW

Elevate your MINI's performance with the Valeo dual mass flywheel conversion kit. This comprehensive kit includes a solid flywheel, pressure plate, clutch disc, throw-out bearing, and more. Notably, it replaces the OE dual mass flywheel for enhanced performance.

If you're missing any hardware, don't worry. Valeo ensures your satisfaction by replacing missing items with your order number. They are also working on an improved box design to prevent damage during shipping.

Designed for the R53/R52 Cooper S/JCW with W11 engines (Supercharged Engines), this kit is not compatible with Gen 2 MINIs (R56) with N14/N18+ Turbo Engines. For an exclusive ECS Tuning kit with extra seals, explore ES3469345.

Upgrade to the single mass setup for cost-efficiency, serviceability, simplicity, and enhanced driveability. Valeo's conversion kit maintains clutch and flywheel weight for quiet and easy driving.

This kit includes a replacement flywheel, clutch disc, pressure plate, release bearing, and more. Please note that a lightened single mass flywheel may result in some "NVH" or "chatter" during operation, which can be influenced by accompanying modifications.

For complete install kits, discover ES3469345 and ES4067131, exclusively at ECS Tuning.

Installation Details:

  • Flywheel bolts (M10x19.5): Tightening torque 90 Nm, Thread lock red.
  • Pressure plate (M7x26): Tightening torque 20 Nm.

If your MINI is only for competition use - autocross, time trial, or racing - this OS Giken LSD may be a better option than the standard 1.5-way unit. This race-spec LSD was developed over several seasons of competitive autocross. It uses a new high pressure ring for quicker response time and faster lockup. This makes it ideal for quick transitions and rapid on/off throttle motions typically encountered on the track. It's a one-way lockup so the car stays predictable under braking and gives the driver more feedback. For street use we prefer the normal 1.5-way setup because it's more progressive during lockup.

The biggest shortcoming of any MINI is not the lack of power - it's being able to put all of its useable power to the ground! The Cooper S is basically a one-wheel drive car and sending 200+ hp through that one tire does not live up to its full potential. A limited-slip differential is essential to any highly-tuned FWD car. The OS Giken Super-Lock is one of the most advanced clutch-type differentials on the market, and a favorite of autocrossers and road racers. The OS LSD for the MINI features ten clutch discs for a smooth and progressive lockup. By putting all of your available power to the ground you're at an instant advantage over the stock open-type differential. You'll be able to power through corners and on rough surfaces instead of uselessly spinning a wheel. Understeer is reduced by giving more bite to the tire that has the most traction. With an LSD in your MINI Cooper S you'll wonder why it wasn't first on your list to begin with (or why MINI/BMW left it out in the first place...).

The MNI OS Giken LSD uses a special 80W250 fluid that must be purchased separately.

This item fits the following BMWs:
2002-2006 R53 MINI MINI Cooper S (6MT manual transmission only)
2007-2013 R56 MINI MINI Cooper S (6MT manual transmission only)

This kit from Valeo is a simple way to easily convert your stock dual mass flywheel clutch system to a single mass system.

Dual mass flywheels allow for fluid-feeling clutch engagements and offer a more luxurious feel than single-mass flywheels. However, with these benefits come significant drawbacks. Why convert from a dual-mass flywheel to a single-mass flywheel?

Cost: Dual-mass flywheels are expensive, with the cost of replacement often times being double or triple than that of converting to a single-mass flywheel.
Serviceability: Single-mass flywheels can be resurfaced, eliminating the need to replace with the next clutch service. - something that is not recommended with dual-mass flywheels, as they contain a rubber section that is more failure-prone in high mileage application.
Simplicity: Single-mass flywheels lack the complexity of dual-mass flywheels, making them inherently more reliable. Dual-mass flywheels contain a rubber damper or hub that will, like all rubber components, wear out with time.
Pedal Feel: Many enthusiasts prefer to eliminate BMW's "Self Adjusting Clutch", which has been known to provide an unpredictable, inconsistent engagement point.
Driveability: Valeo's conversion kit has been designed to maintain nearly identical clutch and flywheel weight, ideal for keeping the clutch quiet and easy to drive.

AutoTecknic was established in 2000 and has since become one of the largest manufacturers and distributors of carbon fiber parts and accessories for a wide variety of manufacturers. Autotecknic has designed gear selector trim for the G05 X5, G06 X6, and G07 X7 composed of 3k twill weave carbon fiber. Includes guide for installation. Dry carbon fiber's name also comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed vacuum (autoclave) to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest quality version of carbon fiber products that are produced.

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

Everyone knows that high heat is the enemy of your automatic transmission. And that higher power levels generate more transmission fluid heat which will cause a trans slip. Now you can extend the life of your automatic transmission by installing the new Burger Motorsports High Capacity B58 Gen1 Trans Cooler kit. This unique plug-and-play kit replaces your factory coolant to trans fluid heat exchanger with a high-capacity front-mounted air to trans fluid radiator. Includes all mounting hardware, lines, and coolant caps required for installation. Installs within the front bumper behind the driver-side kidney grills 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 B58 Gen1 F chassis automatic car running larger than factory turbos. 165ºF (74ºC) transmission oil cooler Improved Racing thermostat included The thermostat maintains the oil exiting the transmission at the rated minimum temperature in most conditions.

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. 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. 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.

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 lauch, acceleration, 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.

With the 135i/335i LSD unit, they have incorporated revolutionary new ideas into the design (4 years in the making!) which 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!). Zero break-in required. Super smooth and quiet engagement, and 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 Superlock 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

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!).
