Hi, i'm looking to fit Focus ST170 300mm discs, Pads, and calipers to my Escort RS and need to know if I can use any Focus calipers or if it is only the ST170 calipers that will fit with the 300mm discs?

Looking at some photo's on ebay it looks like '05 onwards the calipers are the same as the ST170's and will fit!

Thanks for your help!
