I have some 18inch Yokohama wheels for sale, I dont know the exact specs but they fit mk3's and mk4's nicely. you can see pics here www.myspace.com/fandh They're on the front of the grey mk3 in a pic or 2 and on the Silver Mk4. I had them re-done 2 yrs ago so theyre pretty clean minus a few scratches from mounting and unmounting tires.
