I have an oil cooler bigger rad,fans and everything is wrapped with thermal tape. The exhaust is also wrapped all the way to the cat. I run 180deg thermostat with water wetter and control the fans with the ac switch. I also use 10w40 royal purple xpr oil. With that set up all of my temps stay pretty normal under all driving conditions from numerous 30psi lapping days(long time ago) to recent numerous 40psi back to back drag passes. I never was able to run my car hard enough for it to get too hot. As long as everything is working properly you will be OK. As for tires if you show up on some 10 year old all season gems you will very quickly finish them off. Shannonville is a great track to learn things about your car and discover your limits. It will also expose all the short cuts you took when working on the car. Loose clamps, bad\old couplers, loose bolts or overdue maintenance. Even if you don't drive there most people that show up there are willing to take passengers. I always thought it's funny when people show up to race and do 2 laps or couple passes down the 1/4 and have to let the car cool down because the car is too hot. Set up the car properly and you will have more fun with it. Whats the sense of having a car that can put out good numbers only under certain conditions on slicks. I know we all have race cars . So get out and enjoy your car and stop making excuses.
