Unlike with a dual clutch transmission you can only use it a couple of times until you have to replace the clutch. For the M5 and M6 I believe it 9, 17 or 24 times. Someone correct me.

Wow, does lanch control really ruin the clutch so much?? Weird!

Never heard about replacing clutch after using Launch Control .Only thing I heard is that you cant use is over and over again in short period of time..and thats it.

I don't think it's an issue with the new M-DTC tranny though. This is one of the benefits with DSG type transmissions. Much smoother relationship between the transmission and clutch.

It will be ruined if you do LC-lanuches over and over again...

Strange thing is, it is said that the GT-R has the same problem? True?

Well on the SMG, which is like a manual, it's terrible to dump the clutch like that over and over again when you do a hard launch.

I don't see why it would be different with double clutches. Either way, you are still putting a ton of stress on the transmission. I'd almost never use Launch control if I owned one.

I know that on the M3, it needs to go through a cooling faze before you can launch again.

There is no hard limit on the number of launches you can do with SMG. It is no different from a normal manual where the driver dumps the clutch at a high RPM for a good launch. There will be clutch wear in that case too. The same goes for DCT too. In fact it is worse for GTR cause of AWD, where all the slip has to happen on the clutch instead of between tires and the road surface. What SMG prevents is doing repeated launch control starts in a short time to stop the clucth from over heating.

So i guess any car equipped with that type of tranny suffers the same? like SL63 and Scuderia?

Basically the LC is the same idea, as letting the clutch off in a manual transmission car in eg 3500rpm. I do it all the time with my Clio but i still haven't changed my clutch

The clutch would be the least of my worries when spending so much to mod an M6. If you look closesly at the vid, as the car passes 350 KP/h, the cars bonnet sensors pickup that the hood is not closed properly (The sheer resistance at that speed is obviously lifting up the hood). If for some reason the hood was bust open at that speed, one can only imagine what kind of disaster would take place.
