Hi, big rig. How about reverse-mounting BBS LM099/LM100 8 and 10 x 18s with 225/40 and 265/35 Rosso N4s? Estimated net offsets (assuming 15-mm decreases from reverse mounting) would be 41 and 50 mm for the 8 and 10 wide, LM099/LM100, respectively. This isn't too different in set up than my current 8/10 wide Fikse FM-10 in 51/57 offset with the same sized Rosso N4s? The wheels/tires will move 0.4 inches outboard in front, and 0.3 inches outboard in back? http://www.rimsntires.com/specspro.jsp
what suspension are you on?

FYI, BBS USA doesn't recommend reverse-mounting their LMs, as the entire wheel load is carried by the assembly bolts, rather than the mating surfaces between wheel center, rim flange, and wheel bolts. Reverse-mounting LM wheels if the centers were not designed to mate properly will lead to wheel failure.
Also I wonder what BBS Japan's take is...
Some fitments avail via BBS Japan isn't available via BBS USA FWIW.
