As Marc has said you would need to see what wheel clearances you have and offset of wheels plays a big part.
I have to use focus RS 18" wheels on my cortina due to size of brakes.

It's not just disc hub and caliper it would require wheel and upright. It's easier to do on car.
Search on eBay for caprisport, I personally don't like the bloke but some of his stuff is reasonably priced
