Ok so let me get this straight I just need is a set of calipers and rotors from a 05 06 monte to do this? and aren't the montes larger rotors like 13"? and is there really a noticeable difference? Only modes I have are functional ram air and I will be adding headers in the future and that's about it. Also if I decide to keep my stock calipers they are not leaking and work fine but they do have 307,000 miles on them should I rebuild them or just wait till they go?
