Need some 10mm spacers. Was about to order some H&R hubcentric ones... but Read a few forum posts which say 10mm won't fit the A4: http://www.audi-sport.net/vb/audi-s4-a4-a4-cab-b7-chassis/99342-wheel-spacers.html However many people have used 10mm on the A4 according to posts etc, so which is correct? I measured the hub which is about 13mm deep. Given H&Rs guide online I would think I need either 2055571A or 2055571B. The website doesn't state what the difference is between them? One website also has an option for 'radius' or 'tapered' extended wheel bolts (OEM or aftermarket), does this mean that I cannot use the original wheel bolts with my new aftermarket alloys?? I'm sure there's a simple answer to this... Thanks guys.
