I say go for it. Mine is mostly stock, has original CSC, no oil cooler, original brake pads and such. I've tracked mine at least 3 times per each of the past 2 years with NO ILL EFFECTS. I run the car as hard as I can, and it has performed flawlessly.
Your CSC could fail at that high of a mileage, but so can one with 20,000 miles on it. I did have one incident of the clutch pedal going to the floor, but that was 3 years ago at the drag strip. Only happened that one time and then NEVER AGAIN. I may be pushing my luck, but I figure why worry about something before it happens. If and when a problem shows up, I'll take care of it then. Until that happens, drive it like it was intended to be driven...
A little video I shot at PittRace last season if you are interested.
