What size wheels fit over BiTDi front calipers?

Looking to get myself a set of winter wheels for the BiTDi and wondered if 17" Would fit at all, anyone running smaller winter's here?

Not gone that low Phil, but I was up at Skidz at weekend and planned on dropping to 19 rotors with winters.

Mine has 19" twin blades as standard, and they're really comfortable on our roads tbh.
Think I'll end up picking up a set of 18's to use as winter's next year.
