Thanks for the info guys.

CivicSiRacer,
Yeah, it will be used for autocross, but it will also be my daily driver. Since I drove over 50 miles round trip every day, I don't think I want my speedo to be off, my fuel economy to go down by more than 8%, and my cruising RPMs that much higher (and louder).

Does anyone have any specific experience with a 225/45-17 tire and wheel on a 6th Gen Accord? Will it really require fender rolling even if the car is not lowered?

Thanks again,
Joe
