BMW E89 Z4 - 2008-2016 - 3.0L with 7-Speed DCT | DCT-795-AL| Clutch Kit
Description
We’ve got to hand it to the engineers who sat down and came up with the idea
to build a 7 speed transmission that shifts gears in 50 milliseconds. When BMW
implemented their new dual-clutch transmission (or DCT), purists were up in
arms that they could no longer row through the gears using an H-pattern
gearbox (thankfully BMW usually gave buyers the option to spec a manual
transmission). As time went on however, and more drivers got to experience the
feeling of driving a car with a DCT, many came around to the idea.
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.
This dampened hub has become the basis for all of our DCT flywheel builds and
has been tested on the street and on the track from factory powered cars as
well as behind engines that have been extensively modified and the feedback
has been nothing but positive. Word has spread quickly within the DCT
community that our sprung hub setup is the ticket to a smooth and reliable DCT
driving experience.
