you can buy a complete bolt on kit from rally design dude, go look on the site and see what they use, i think its 500-600 quid. but you get pads, disks braided lines, brackets etc so full on kit. maybe not as cheap if you cn get people to do brackets but at least its all bolt on. if not go in the mk2 section on edition i think there was a thread on there last week or the week before about whats the best brakes to get over g60s, to be uber cheap or at least to will woods you can get s2 two pot calipers which are a g60 alternative
