just scored a full 96 itr brake conversion complete with 96 itr wheels and tires for 690. now im kinda stressin since i cant find any rotors to replace the rusted ones. someone told me there the same size as the gsr rotors and same goes with the calipers, is this true, where do i go to get the brakes re-drilled to 4x114.3 and how much does it usually cost? i also heard i can use 4th gen prelude rotors and that they bolt in but i might have some caliper issues, so does this mean i have to get prelude calipers, cause ****, those things are kinda pricey....any help is well appreciated, thanks
