I would go with a neutral color so it matches everybodys car (matte black) and thats coming from somebody who would love silver...

I had a turbo rx8 and lived in ca, trust me from experience that its better to go black and look stock!!! If you want badging, have it not that noticable and do not put turbo anywhere on it!!!

I like your quick badge design by the way.


My 2 cents....
