13" ATS + MK2 brakes

Hey all,

I wanting to put 8X13" ATS classics on my VW Caddy but i'm wondering what size brakes i can fit under them?

I was looking to use 256mm MK2 discs and whatever calipers fit over them (Audi 80?)
However i'm guessing these wont fit with 13" wheels?

If they wont what do people reccomend?

Cheers in advance!

Ed
