Man, Sam, if this were true then no aftermarket clutches would be available for this car and no one would have swapped. It seems that all the builds I've seen come out of GTM have an OSG clutch/flywheel combo. Why?

Hell, If something ever happens to my upgraded clutch I'm gonna go back to the stock, per your advice, if that's the case.

I don't doubt you can make it last or that it can last if you rarely put those TT's to work the way they should. I don't mean thrash the car either, good driving means smooth driving, but even so, the stock clutch is not meant to hold 400wtq+ and most will eventually slip if not fail completely. Torque comes early on the tt and as you know that means a whole lot more load and stress on the components. Most of the power is made up top on the SC, hence my comment about the TT needing it sooner.

Now as far as removing the engine. Taking the engine out of the car for a TT install saves money because less time is spent on labor of installing the rest of it. Hence it makes sense to remove it. It's not that you CAN'T, I'm aware that you can, but it will take longer and if you're paying labor that doesn't make any sense. Most of the people who choose to do it with the motor in it tend to be doing it in their garage without a time restraint.

Please don't view this post as a I was just trying to help the OP with info. You actually kinda proved my point though... you posted links that show a TT install is $3,000 more than the SC. Also Flyboy posted his quotes for the installation of SC vs TT...its twice as expensive just to install the TT.

I don't see what the problem with that is, you also get twice the torque and crazy expandability. TT is a great option, but people should be aware that it will be a little more expensive for various reasons. If you don't think a clutch should be recommended and install should be done with the engine on the car, well that's your well informed opinion. I also don't think saying the opposite is being "full of misinformation".
