On a spirited run today I noticed the clutch slipping on higher revs 5k+ 3rd/4th on WOT and full boost up to 21psi.

When I stopped at my designation I could smell the usual clutch burning smell.

So... I need to look for a heavy duty replacement that can handle with spare capacity over 650nm torque.

Can I have some suggestions on ones to look at.
I'd need the cluck kit and replacement flywheel.

Thanks.
