The actual calipers cost me £200 few bits and bats to get them upto scratch so calipers in total to how they are now £250 plus the fitting kit ontop around £500 in total,
You could easily exceed that if your having to buy new discs and pads on the S3/R32 set, the good thing is you can buy discs for the gti cheap enough and pads for the porsche you can pick up for the same has the GTI/VRS.
