I dont know what you really gain from the rotors and pads compared to new calipers , but I also am thinking of upgrading, Id like to get 4 piston calipers but thats alot of denero, I looked at the bat kitt group N rotors with tuv approval, I dont know about the power stops for this application, but I know people who have used them and didnt have good results. Iam not mechanically enclined but if you got front calipers for your svt could you then put those front calipers on the rear.
