One issue with the factory BMW DCT setup is the incredibly heavy dual-mass flywheel. There is no clutch so the rotating mass stays pretty minimal overall, but we noticed there was definitely room for improvement. From the get go we knew we needed to develop a sprung hub setup to help dampen any harsh vibrations being transferred from the engine to the transmission in an effort to help protect those clutch baskets inside the transmission as they have been known to crack when using rigid, non-dampened, flywheels. We took our dampened clutch disc technology that has proven itself time and time again to be incredibly robust and reliable and meshed it directly into a dampened hub that bolts to the flywheel. The lightweight sprung flywheel allows for quicker shifts and faster revs while maintaining maximum dampening during hard, high RPM shifts, and stop and go driving on the street.
