DCT failure?
Folks, I want to know if anyone is aware of any DCT failure due to JB4+FBO+Meth on a N55 ? I am currently FBO and want Meth but am afraid of the DCT. I heard some DCT slips or things like that, any experience shared is highly appreciate it, thanks guys! If it slips, what does it mean for the reliability of the trans ?

the clutch will start to slip after 420 torque or so.. Bu tjust don't go crazy on the launch control and you'll be fine

Why not upgrade the DCT?

I believe the M3 dct clutch pack upgrades could probably be used to beef up the transmission. Haven't heard of anyone doing it on an N54/55 car just yet.

I understand that the M3 would likely have beefier components overall but do you really think BMW would overbuild the M3's DCT to handle nearly double it's stock torque output? If anything, I would expect the M3's DCT to be designed to handle more revs but I don't see any reason for BMW to build it to handle that much additional torque. |

The two transmissions are actually the same (different part numbers due to different output shafts), with different software to control all the settings the M3 can set the transmission to. I was referring to the clutch pack upgrades the M3 guys get when they supercharge their cars.

Yeah, I thought the DCT in these cars were the same with different software and of course the M3 gets the real LSD. |
