This will give you idea the beating my car takes at the track. This is a picture of my wheel weight. I forget to put a bead of silicone on the perimeter of the weight as I usually do.
On a high speed track my wheels run aprox 250 degrees. To check and adjust tire pressure requires gloves. My calipers that day where 400 degree front and 300 rear.

Wow, that is a lot of heat. I assume you are not using a stock brake set up, so what have you installed, and how long do your pads hold up?

Im using Wilwood calipers, Coleman rotors, Performance Friction 01 pads and 3 inch brake duct at the front. Front pads are .80 thick with 1 3/8" thick rotors. They take a beating and last quite long. Stock brakes would not handle that abuse. See my website for pictures and list of car setup.

Im impressed that they stayed on there!!! I throw weights all the time but must end up in a ditch somewhere.

I never thought of putting silicone on there. Great Idea!!!

Mike, thats remarkable. I wanted to thank you for your encouragement and assistance earlier in the year in diagnosing my car and providing advice on HPDEs. I participated in a PCA event in June at Watkins Glen and thoroughly enjoyed myself. Its clear that I need at least some ducting to cool the breaks, though, as my stock setup faded badly after about 20 minutes.

Thanks again.

Im glad to be of help. Feel free to contact me for any thing. What specific club do you go to Watkins Glen with?
If you think tires dont shift on the wheel, heres a picture showing what happens. All my wheels and tires get marked and all my wheel/tires shift if subjected to heavy use. Mounting is done with a soap lub only, not any silicone based crap that would probably have my tires spinning full circle.
