[QUOTE=thstone;593916]I go through 2-3 sets of rotors per year and over the past 8 years have tried everything from the most expensive to the cheapest and never noticed much difference. [QUOTE]

I'm with Tom. I warped my orig front rotor after my 1st time at COTA. They don't allow a cool down lap and I just came in and parked. Looked at ordering some but found some zinc hat Bosch at the O'Reilly down the street. They were cheaper than online and I hadn't even checked what shipping would be. Those suckers are heavy and would have to cost a fortune to ship. The Bosch's have worked great now that I do some cool down on the side roads (have done COTA twice since and Indy 3 times).
