larger caliper on the oem rotor- no thanks. the rotor's ability to dissipate heat is just as important (maybe even more important) than the caliper. i think with the enlarged pad size (lets pretend it is double) is just going to put more heat into the rotors and overwhelm them sooner. these oem rotors can't get rid of the heat well enough to run that large of a pad.

they are probably fine for the street, but if you plan on tracking them, i would speculate this is a very bad idea.
Why would you speculate that when the guy who is doing it tracks his car a lot and says it works great?
