Wow, I'd not seen the brakes up close before, at least not until those on PJ Jones car exploded. Those are thick pads on those cars. I had no idea they were that thick, even after half a race. I did notice his rotors weren't drilled though. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/tongue.gif)

A lot of the bigger cars will run inline fans in the ducts to help cool on slower parts of the track. I don't know if its legal in cup or not but they might even be using water misters and spray bars for even more cooling but I don't know if they allow water cooled brakes.

I think the rotors on the road course cup cars are probably 40-44mm thick, pads are probably at least that on each side. Thats a freakin huge caliper.

I don't believe that any professional series allows water misting of the brakes anymore...except for the diesel truck guys. Something about failing rotors...

Also, the wheels can put bigger brakes then you think underneath. The steel wheel can provide more clearance then an alloy wheel. Steve can comment more on this as those are the same type of wheel he uses on his stock car. I imagine they are at least 13" rotors with large 6 piston calipers that are not "off the shelf" parts due to the thickness of pads they are running. They have custom caliper halfs with thick spacers between them to allow for the thick pad.

Anyone have a rulebook???
