probably not worth it on a car like this.....Don't use OEM rotors if you can help it also....They're a tad on the undercapable side for road racing, even at 2200lbs
Are you allowed to uprate brakes? There has to be a bigger OEM rotor setup you can use? You probably don't need anything fancy....just some bigger heat capacity, you know?
I know the 99-00 civic Si can use Corrado G60 along with some other OEM Honda caliper (Legend? I can't remember but a coworker has this setup on her race car)
