Looks sharp even from afar. Too bad the file size here is so small (admin?).
That's light, very. And even certainly lighter than even what Forgestar had told me. Had been talking about 18x9" also for an RS6. Nine inch is a better width for a 255, at least for handling. Audi runs the narrowest tire to wheel ratio of nearly any euro manufacturer. Some tire companies won't sell the wide width of tire needed unless it's specified for a specific Audi (A6 4.2 with sport pkg is one).
Nice with Forgestar is the custom machined off-set per request, or to match OE spec. No spacers. Downside is 4-6 wks lead time to make them. Upside is they are USA forged and reasonably priced from the right source. With my factory direct wholesale connection, also intend to get a set. Likely some wide 18's for hard driving. But then again, when switching back to the stock wheels, they seem to roll heavy and thump, even shudder on certain bumps (with Michelin AS-3's no less). It's not "bad", but annoying at first. The summer wheels are 7lbs lighter, making for a noticeable difference in how they role and ride. Why Audi used such heavy wheels on the RS6 may just boil down to a cost issue...
Dealing with aftermarket lugbolts, with spacers, is usually a bit tricky and a compromise. Better for bolts to be too long than short. There is plenty of room past the hub flanges.
If memory serves 27-28mm is stock, add thickness of spacers, factor in wheel hub thickness (it may vary with custom wheels; offsets). Mine comes out to like 38mm, and use 40mm bolts, with 10mm spacers. FYI- if using exact length bolts, closely . inspect the first 1-2 threads. Most import bolts (in general) have or can have a pronounced taper, reducing thread engagement. It's recommended to check for actual engagement (rotations, something like 7 to equal 10mm).
Quite interested to hear how the wheels effect driving dynamics.
