great points fattie and very imformative...although Troy did encounter problems with over heating C5's but it was if you remember 110 degrees out, he had no direct ducting and did it to beat up on two Porsches. So in all reality did fairly well.
I still believe high temp fluid and direct ducting would have helped.
As far as factory C5/C6 brake usage is concerned? Not too sure, might be the belief that factory is crap? I think the C6 Z51 set up is more than adaquate for a hard driven street/ moderate track car. The Z06 package might be overkill for some but will be fine for the harder racers.
Personally I hope they keep looking the stuff over cause it makes it cheaper for us regular guys to get. I use the C5 set up on 2 of my cars and the performance is more than I need. vin
