Hey Sparky, fellow '15 black STi owner here from the other side of the pond!
I absolutely love what you've done with your STi! Quick question: would you mind telling me where you got the black Subaru star badges from? Also, it seems like you replaced the outer ring of the badge from chrome to black too? Can you let me know where you got that too please :)
Btw, have you considered changing the caliper color? Someone over in the iWSTi forums posted this picture of his yellow calipers on his black STi. I think it looks so much better than the black calipers. I was also considering doing mine either yellow or red...
