they make brackets, intented to convert 3000GT non-turbo cars' brakes to the twin turbo cars' brakes. those same brackets can be used on DSMs to fit those calipers onto our car, so then you get absolutely gigantic brakes for not that much money. 12.5" rotors up front with really nice calipers :D I think the rears are 11.7" but I'm not sure.

I haven't been able to find the brackets again, but I do know they exit :D you will definitely need a certain kind of rim to fit those brakes, though, I think it was FlyinESi that said his HP Racing Evos wouldn't clear the calipers on his friend's Stealth RT.
