DD, that's funny that you hate PBIR, I like it for testing. The two long corners (that I remember, only been there twice) are great for feeling out front end grip and to see if the rear end is behaving (with a lot of run off room), and you can lap it quick enough in a 10 minute session to keep mental notes of that same corner without any brain fade. I wish I had a track like that near me, most of them up here that are short don't have any such features- short tracks have silly, speed killing tight turns, long tracks have big, high MPH sweepers.

As an aside, it is hilarious that folks have inured themselves to a clutch & PP being "wear items".
In 102,000 miles, of which probably half are on track, my full-race M3 is still using the original PP... And I have replaced the clutch once...only because I also put in a lightweight flywheel at the same time.

Don't ride the clutch and it'll last a long time. Abuse clutch, abuse wallet...

My old Skyline GT-R's clutch was a wear item after a 200hp bump. At stock levels, going from the OE full organic disc to a three piece semimetallic sprung hub disc made it a 4 year "major" item. At the power the new one has now, I use a custom Tilton triple plate carbon/carbon clutch with hydro throwout- used clutch from the WC car back in 2006. That thing has seen all the practices, starts and wear from 1/2 a season of WC racing, virtually no wear @ "500hp". Should be perfectly fine for street driven 700whp (approx. "500hp" on the SCCA WC cheater scale).

Peter, the long slow corners are really good for testing chassis especially if you are trying to break down suspension/alignment/weight jack transitional states (before I got the SoloDL, which makes it even easier now). I could literally try three or four different things per corner at PBIR to see what and what does not work, and after four laps I had more than enough data to move towards a much better setup. I guess horses for courses, PBIR is great for testing, probably not a "track day" epic track but realistically, how many of those are there in the nation. For example, for me to get the same data at GingerMan (there is only one corner like that there) I would have to be on hot laps for literally 4 times longer and only get about 2/3 of the data. I like driving tracks, but I hate poor use of track time, and more importantly, my own time. PBIR for me is a 2 hour dealio, but to do the same thing at GingerMan would be a whole day affair.
As for your clutch issue, why not just get an aftermarket disc and be done with it? If they are overheating (PP or disc) that mean slippage, get something in there that doesn't slip, and it's taken care of. Again, my pet peeve is wasting time- constantly swapping out OE clutches would cost me more than just paying for something that actually works properly. Either way, that sucks if the OE clutch does that. My S2000 OE clutch wore out the springs on the disc early in it's life, swapped it out for a Mugen disc/PP, no more problems (10 years on that clutch now I think). So I know how you feel.

The Ferrari Club had the day reserved and when they bailed, Sebring offered it to Pete. Pete drummed up some interest but not nearly enough to make it economically viable. He called Henry Gilbert of HOD and Henry sent email invites to his instructors, advanced drivers and friends a couple weeks ago and he filled it up in five days. It was a grat day. Roger had several Cup cars and a full crew.
