Goodrich hoses (or any similar manufacturer) make a difference to any machines braking imho.
AP calipers are the way to go if you have more moey than you know what to do with Tony Smith had some PVM calipers with cast iron discs on the S he sold last year but found that the discs wore at an amazing rate and then warped
As Lloyd has already said,you can either go PVM or AP neither are cheap but good things never are,and he forgot to tell you he's just about to have some fitted, AP's that is!!!!!!!!!.
