Well why doesn't Honda just make the car with 18x8.5" then? They effect performance. Too much rolling mass. A 17x8" is perfect for the new Civic. Bigger is not always better, and most times looks stupid.Why would you not want 8.5" on a coupe? I would love it if the my Mugen GP's were wider than 7.5".
What does the +45 offset mean. What size does the stock come with? What size would be wide enough just to be aligned with the body of the car?
