Ah yes, the age-old question. "Silver or gold?"
Silver wheels compliment the silver metallic flakes in the DGM paint. When I had the 2011 STI Enkei wheels mounted I always got compliments because I think those silver wheels really complimented the DGM.
Gold looks good with the gray paint, though. Kinda like how bronze goes well. There's just an earthiness to the DGM that has appeal, so throwing gold wheels on kind of compliments the color. The biggest issue is that with the WRX sedan we have the chrome on the window trim. Get rid of that and everything should be good.
