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

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.

This 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. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

This Bav Auto 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 can produce knocking sounds and 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.

The SPEC Stage 2+ clutch is a premium, no compromises heavy-duty clutch upgrade for the 2001-2003 E46 330i/ci (5-speed transmission). It goes beyond the standard Stage 1 upgrade with a higher-capacity clutch disc rated at 545ft-lbs! Where the stock clutch is well-known for premature wear when driven hard and the factory dual mass flywheel is a known failure point, the SPEC clutch delivers with an over-engineered, performance-oriented clutch solution.

The stock 330 clutch was not designed for performance. It works fine for a daily driver street car with no mods but performance and longevity quickly drop off when adding more power or using the car for aggressive street, autocross, or track use. A lot of our customers also hate the self-adjusting clutch (SAC) mechanism and the clutch delay valve that makes clutch engagement inconsistent and unnatural feeling. It's no wonder that for the Grand-Am Cup touring car races the rules specified an E36 M3 clutch! If you're unhappy with the stock clutch feel or your future plans include additional upgrades that boost torque, then a heavy-duty clutch is what will be needed. The SPEC Stage 2+ clutch consists of a carbon-Kevlar friction material paired with a heavy-duty pressure plate. The clutch is stronger and grabs harder than the factory clutch. It has a much more robust feel and engagement. And with this specification the clutch will never be a weak point. The SPEC clutch is designed to work with the stock dual mass flywheel or with a lightweight aluminum single-mass flywheel.

The real weak point in the driveline is in the flywheel. The stock dual-mass flywheel has rubber damper discs inside that will wear out over time. Heat and aggressive driving will accelerate their wear. Even if the clutch contact surface is not showing wear the inner rubber linings most likely are. On most clutch replacements we strongly advise getting a new flywheel at the same time to avoid duplicating the work. You can use the SPEC clutch with the stock or an aluminum flywheel. A machined steel flywheel is also an option as a middle ground. Both the SPEC steel and aluminum flywheels are lighter than stock and will be single-mass. There will be a lot more noise and 'gearbox chatter' with the aluminum but the tradeoff is a much better acceleration and quicker revving. For daily driver commuting you will probably be happiest with the stock flywheel. For the ultimate in sports car feel use the aluminum.

SPEC Clutch is one of the premier clutch and flywheel suppliers to the tuner market. They are often found on the most highly tuned import and domestic vehicles. They are recent players in the German car community with a special focus on the newer turbo BMW models with high torque output. SPEC has been proven time after time to provide superior performance, drivability, and longevity to the most hardcare enthusiasts around the globe.

E46 330 SPEC Clutch Kit contents:
+ carbon-Kevlar clutch disc
+ heavy-duty pressure plate
+ heavy duty throw-out bearing

This item fits the following BMWs:
2001-2003 E46 BMW 330i 330ci 330xi only for 5-speed manual transmission

This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
