dont think brom will do another 315mil disc conversion with focus rs calipers, he said it was a bit akward when he done mine

i would say cossie 4pots and alloy bells and 300 mil rotors, then get a bracket to ake em fit and ya sorted for very little money

but first place to try at any poinmt though is brom@zoo as hes the only one id use for my brake conversions as hes a fookin wizz with em and a fooking top guy
