rs turbo calipers and 4x4 calipers, whats the difference?
 

as above im looking at changing to the 2wd disc and 4x4 caliper set up on my s2,

what the difference in calipers from the s2 and cossie?

ive got them on my s1..they are a lot bigger than the standard ones..tight fit behind standard wheels..im just having bother getting mine to work

a good upgrade, done the fronts on my turbo cabrio, standard rear drums, stops well
