Can anyone tell me how much room there is behind a set of 17" Mo's?

Im after fitting a set to my Escort, i am running Cosworth brakes on the front and they have had to be spaced out 6mm from the hub and im wondering if the calipers are going to scrape the wheel.

There is shit loads of room behind the current wheels and they only just fit.

Cheers lads

 

i have ap six pots with 355 mm discs behind MO's.

as much as you will need unless you have to run bigger discs

 

Cheers mate it wasn't the discs i was worrying about it was the fact the calipers are spaced off of the hub.

Thanks again
