Personally, I don't like the wing on the back. I suggest that you take it off and replace it with the more tasteful factory wing. As for the gas. I agree with everyone else, always put premium gas in a turbo/supercharged car. also, cops dont need to have a "reason" to pull you over. They can pull you over for nothing and say that they saw something or other stuff along these lines. trust me they have done it to me and my car is completely stock. Anyways, good luck with the car. if you paint it I suggest black or deep blue.
