Granted I have no direct experience running the 712's on the track, but I have run Dunlop D60's and Bridgestone RE30's on the track. What I was advised to do is to start with a cold pressure of about 5 pounds under the max street pressure (I think it is 44 pounds for the 712's, so that would be a starting pressure of about 39 pounds). Measure the pressure after your first track run and adjust the hot pressure to about 5 pounds over the max street pressure (so about 49 pounds). I know that this sounds controversial, when I was first advised to do this I was very reluctant. However, what this achieved in my case was to increase the sidewall stiffness of these street tires closer to track tire specs and reduce sidewall flex. This kept the tire from rolling over onto the sidewall (which has very little traction compared to the tread portion) and reduced the amount of feathering and chunking. This was were I first learned of the Rebco pressure regulating valve caps. I never went that route opting for track tires and wheels instead, but maybe worth investigating. One more little tidbit I will pass along: Do not set your parking brake after coming in from a hot run. Leave the car parked in gear instead, use a wheel chock if you are otherwise concerned. The parking brake will keep the temperature of the rear discs higher where the shoes touch the disc, not allowing the disc to cool evenly. This can cause the discs to warp.

Yes, I know about the parking brake, I have quite a bit of track experience and a dedicated track car. The M3 is the backup, and may be put in service due to a towing vehicle issue. Take care!

I think it was maybe Marco Romani based on an idea by Bob Tunnel. Or maybe vice versa. Or maybe that's my internet-saturated brain...

Well looks like I have some minor rust bubbling up on the rear fender = lip right above the wheel. Is there any chance to fix this problem long = term so it does not come back?

#9. Bad Wheel Bearing? - from Peter Guagenti

Date: Sat, 29 Jun 2002 22:36:33 -0700 From: Peter Guagenti <peter@guagenti.com> Subject: Bad Wheel Bearing? After a hard day at the track yesterday, I'm now getting a grinding noise from the DS wheel. At almost full lock turning to the left, I'm hearing a grinding noise. I haven't jacked up the car to see if something is rubbing, but since it came on fairly abruptly, I'm wondering if it could be something not caused by contact. Any advice is appreciated. Thanks, -peterg

#10. Time to touch up the paint...any tips? - from Chester Wong
Top
Date: Sun, 30 Jun 2002 20:57:27 -0700 (PDT) From: Chester Wong <chester_p_wong@yahoo.com> Subject: Time to touch up the paint...any tips? Well, we had a fun day at the track (Pocono) on the long course this past Tuesday. Five 25 minute run sessions! Probably put about 150 miles on the car...even ran out of gas...well, got gas starvation in a left hander so I had to retire from my 4th run session a bit early to get gas :) Anyway, went to Wayne's place on Saturday and washed the car. Busted out the 3M hand glaze and buffed the whole hood...got rid of all those rubber marks on the hood :) So I got home and noticed a mark on the hood...thought I missed a spot. So I pulled out the car to wax the hood today and noticed that the mark wasn't made from a rubber tidbit but something I must have picked up on the way home. I now have an ugly scratch (all the way to the primer/sheet metal) =( So...any advice, tips, product recommendations, techniques, etc.. I've already seen Jim Powell's writeup.
