Hi guys, Considering getting some new whelks for the TDI but I can't seem to get my head around the width/offset thing!! So I thought I'd just come right out and ask if the specific wheels I want will fit; they are - 18" 8.5j ET42 (front) 18" 9.5j ET40 (rear) ?? if the rears are too much will the same 8.5j front and rear work? cheers...and sorry this has probably been covered a million times, gary.
