. I want to upgrade to 10.20 rotor what type of wheel spacer do i need? and caliber?
Personally, I wouldn't put a wheel spacer on anything. There should be some kits available that have the equipment you want. Are you racing the car? Of course, placing larger, aftermarket rotors on the front will upset the the braking bias the vehicle was designed with. I would recommend doing all of the brakes at once for safety and performance. You'll probably need to change the calipers too, and eliminate the ABS system if it has one. Racing right? I wouldn't mess with the brakes for everyday street driving because trial and error can become deadly.
