Wait, do they actually look 100% identical? Because I've always felt they looked different somehow... perhaps it was the photos. VMR has some AWESOME pics out there.
I'm interested in a set of 18's within a month, so if anyone could point out the differences for me that would be great..
EDIT: M310's don't come in 18x8.5 or 18x9.5, so VMR it is.
but I'd still like to know the difference. If the M310's came with the gunmetal/machien face in 18" sizes with .5 wider widths... I'd get it instantly.
