Clutchmasters BMW DCT 6-syl. (8-bolt) dampened flywheel

Clutchmasters dampened DCT flywheel for 6-cylinder vehicles (8-bolt crank pattern), for instance BMW 335i E9x N54. Kudos to the innovative engineers behind the 7-speed transmission with 50-millisecond gear shifts. When BMW introduced their dual-clutch transmission (DCT), enthusiasts were initially resistant to abandoning the H-pattern gearbox (thankfully, BMW often offered a manual transmission option). However, as more drivers experienced the DCT, opinions evolved.

An identified flaw in the factory BMW DCT setup is the excessively heavy dual-mass flywheel. While the absence of a clutch keeps overall rotating mass minimal, we observed room for enhancement. Recognizing the need to mitigate harsh vibrations from the engine to the transmission, we developed a sprung hub setup. This setup employs proven dampened clutch disc technology integrated into a hub that attaches to the flywheel. The lightweight sprung flywheel enables faster shifts and revs while offering optimal dampening during high RPM shifts and stop-and-go street driving.

This dampened hub forms the foundation of our DCT flywheel builds, extensively tested on both streets and tracks—whether behind factory-powered cars or extensively modified engines, feedback has been consistently positive. The DCT community has quickly recognized that our sprung hub setup ensures a smooth and reliable driving experience.
