Will not fit B7 RS4 without a spacer.

Re: is it okay with spacers
 

Will I get an 18inch without a spacer.

Call Tirerack...
 

I'm willing to bet you could actually get a number of 18" wheels to fit without spacers. For instance, there are a number of 19x8.5" BBS wheels that fit and their 18x8.5" counterparts should work also. Still, unless you plan on regularly driving your RS4 in deeper, heavier snow, just get a second set of stock wheels and stock sized snow tires.

Re: Call Tirerack...
 

I agree. Let me call tirerack. so 8.5 is the key number right that clears the calipers.

Thanks

Yes

There's more to it than that
 

Wheel width alone won't be enough. Spoke design is also a factor (along with radial clearance). Call Luke at the 'rack.
