I have a set of DPE GT-7's with steplip in a custom discontinued titanium asphalt finish.
the bolt pattern is 5x120, made for bmw's.
fits non-M's, but with spacers and thicker tires it will fit m3's no problem.
some pictures of it on the car. - Edit: will post new pictures up soon. Wheels are off car and ready for purchase. New wheels have been purchased so no need for these.
