After experiencing many issues with the factory E46 M3 six speed Getrag transmissions we have developed and rigorously tested a custom clutch/flywheel assembly kit for prolonged race use. We found the ZF six speed transmission has much stronger internal parts than the weaker Getrag. The ZF transmission is also significantly cheaper and more readily available.
Our Achilles Motorsports Race clutch & flywheel kit is made up of a custom SFI Certified Chromoloy flywheel utilizing a 5.5" Tilton race clutch and hydraulic release bearing that is designed to eliminate the stock type fork arm, pivot balls and external slave cylinders. The constant contact design of the Tilton hydraulic release bearing maintains positive pedal feel even as the clutch wears. The hydraulic release bearing also self adjusts to wear.
The purpose of our kit is to allow the installation of late model ZF GS6-37BZ six speed transmission in the E36 and E46 3 Series chassis with a simple driveshaft and transmission brace modification. The kit will fit without driveshaft modification in the E46 M3 chassis because it has the same physical dimensions as the original Getrag six speed transmission. The only part needing to be replaced is the shifting mechanism(from a E46 330 6-Speed ZHP 03-Up).
We have used this conversion in our own E36 M3 racecar for the last 6 years and it has performed flawlessly. We also used this conversion in our latest E46 M3 enduro car tested over the last two years and achieved a podium finish at the 2012 NASA 25 Hours of Thunderhill Endurance Race.
