Looking to put a set of 20" staggered on my '09 SE. In doing so (as I know many have done this) I also am looking to replace the rotors and pads, but am thinking should I go up in size to the R/T size 13" rotors and calipers. In doing this, would I also need to replace the master cylinder, or would it be able to handle the increase in volume needed to move the pistons. I'm only looking for advice from those experienced in brakes, or if you've gone with bigger rotors already.
