First off, I'm new here so Hello. I have a 98 V6 and I need to replace the rotors and pads. I'm running 17s off a 96 cobra. I have already decided to upgrade the front to 13" rotors and new calipers. My question is, should I bother to increase the rear rotors to 11.65" or just get direct replacements for stock? Is the extra money required for new calipers in the rear worth it? Thanks.
