Damn nice wheels! Tempting, not only for the ///M but for the little piggy too (E92 M3) which could use a diet....
So are you guys running these wheels as exclusively for track days, mixed use, or street use?
Since they're lightweight flow-formed cast (but not gravity cast), I wonder how well they'll hold up for mixed or street only use (ridges, potholes, etc.).... At under 20 pounds (fantastic) there's simply less structural material, and forged > flow-formed cast in strength given a wheel of the same weight. Maybe this is less of an issue with the ///M 3,200 pounds than the M3 3,700 pounds?
Anyone care to opine on street/track use and the concerns in the paragraph above?
