Got all ofe the parts and it all bolted up in less then 2 hours and what a differance stops on a dime. When i did a search on the subject and there was some questions abot size diff on the calipers the 2 door the piston was 1 3/4 in and the 4 door was 2 1/8 (give or take a bit it was pouring i was soaked) the whole caliper was a lot bigger and stronger looking and the vented rotor is nice as well. the one thing was the backing plate I did not have to trim or bend at all Is that the norm or will there be a problem later on. The pics of the calipers are here. Thank you every one for yor help Chris.
