i dont think so...
i think 2wd discs and calipers fit as well, providing you have the special mounting brackets...
4 pot calipers, from a cossie... get them
we have had a right headache with this this week yes you can get them to fit however you will need nearly 15mm wheel spacers to get them to fit behind the std s2 alloys, which is a bit much really looked like an offroader and caught the arch on full lock...............................not good, need after market alloys with enough clearance as std or some 2wd alloys
