The rotors are bigger than the Basic brake rotors. Oh your talking about the 4 piston calipers. Okay, the 3000gt had dual piston calipers and the VR4 had the 4 piston ones. Im not sure if you need more with the 4 piston ones. It might be hard to find the 4 piston calipers for cheap but theres always used ones on ebay but you'll definitely the mounting brackets with them.
