Hey chaps, bought a set of 2wd Cosworth 4 pot calipers from the market the other day, i've been reading up but there seems to be many conflicting answers! I know I will need to machine 4mm off the mounting face for them to fit and get some new brake lines and 2wd discs. However it looks like the set up won't fit behind standard RST wheels without significant spacing. I've bought a set of flat face Comp MO5s, and was wondering if anyone has experience with this set up?

Cheers,

Nos.
