BMW Drivetrain Parts for BMW Z Series E85/6 (2003-2008)

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.

Looking to upgrade your stock clutch to something a little more beefy?  The performance clutch kits from DKM are a great option to help get power to the wheels without breaking the bank. Working with Competition Clutch, DKM clutch discs and plates are constructed using quality materials to obtain greater strength and heat tolerance than OE clutches, helping to prevent wear and tear while still giving you increased toque capacity for quicker shifts and more power management.

Stage 1 Kits are best for moderately modified vehicles that want to add a single mass flywheel for quicker revs and a sportier engagement, without adversely affecting the clutch pedal's feel. *This is a 10 Spline clutch kit.*

This Stage 1 performance clutch kit includes the following items:

  • Pressure Plate
  • Sprung Organic Disc
  • Iron Single Mass Flywheel
  • Pilot Bearing/Bushing and Throw-out Bearing
  • Alignment Tool

     

**For vehicles with 5-speed transmission only.

This replacement "sprung-hub" clutch package is designed to work with our (JB Racing) lightweight aluminum flywheel  520-010-240 for the BMW E36, E46, Z3, and Z4 models. The Sachs HD clutch disc has a sprung hub to minimize noise and vibration and organic linings to give the feel and engagement of a stock clutch.

The Sachs HD pressure plate will clamp with greater force -- allowing approximately 350 ft-lbs of torque, which makes it an obvious upgrade from the stock clutch kit.

Because Sachs is an OE supplier to most German cars, replacement parts are just a phone call away. This kit uses the stock throw-out bearing (included in the price!).

**Not for use with stock flywheel or other brands of lightweight flywheels**
