Funny you should ask. I have requested a wheel be lent to me for test fit of this very application for the Focus kits. Seems the supplier won't return my emails....
I'd say that diameter is not a problem, but most factory wheels simply don't have the proper caliper clearance to the spokes. My bet is that they too will require spacers of some sort. Will advise when I find out for sure.
Sean, your kit is on hold for a back order on calipers from Wilwood (can call to confirm if you prefer) and they tell me that the NDLs as well as SL6 I have on order will not leave Camarillo until next Wednesday. I apologize for the dealy, but shipped out a couple of Focus kits that depleated stock prior to yours.....
