B5 -S4 alloys
 

hello all, just after some advice really, i've been offered a set of audi S4(b5) 17" wheels,
just wondered if they would fit straight onto my car-1999 A6 Avant?, the offset on my
current wheels is ET42 -16" ,compared to ET45 -17"on the ones i'm looking at, would this be such a difference,as to need spacers etc?
cheers chris
