Yep, same here. Clean the clutch jet out and make sure the clutch pack is assembled as it says in the LC8 manual. I had given my clutch pack some heavy work on a 2 day rally in Wales a few months ago. In the end I had to refinish the steelplates as they had been over heated but none were warped and the fibre plates were still in spec.
You definately need to keep on top of it to get the best performance.
