We are still waiting on this one... |
Note: We have developed a custom firmware to be flashed to the DCT TCU to gain a higher clutch pressure, only available if you send an TCU to our location in Sweden.
Note: Always do a DCT clutch relearn after a clutch upgrade!
Dodson Sportmans plus (950Nm) DMS-8002 clutch kit.
SSP SPEC-R BMWSPECRPKG clutch kit.
Both of the above DCT clutch manufacturers are very good clutch kits, nothing bad to say about them, the both work!
Note: All DCT clutches suffer from the same problem though, high torque application and clutch slip, in a matter of seconds you can destroy the whole clutch package, make sure to not exceed its limit. We have added a safety protection in our MTune DCT Settings.
Do you really need it?
You will sleep better if you have as much car parts as there is...:)

Both SSP and Dodson offer these "heavy duty billet" baskets.

At 1230Nm (with 15.5bar clutch pressure) with the Dodson Sportman plus (DMS-8002) started to slip, the clutch is specified to handle 950Nm.
We passed 1400Nm (with 17.2bar clutch pressure) with the Dodson Sportman plus (DMS-8002) did not yet slip, but we at this point stopped pushing the torque levels.
