They are 17*8" (44ET), but no gun metal. Closest thing is bronze. I really wish that they had anthracite though or even a grayish tone. It's tough to judge colors from a catalog. They fit very similar to a 17*7.5 Rota on a WRX (wheel protrudes ever so slightly from well..1/4")
Volk actually calls out in the catalog what wheels fit the suby brembos.
