The wheels by themselves look good, but just a little bit too big on a Forte....I think the best fit is 17" to keep your handling as stock as possible, but I also think 18's aesthetically is the best looking fit, but then you are losing some handling I would suspect. I am actually torn at this point between 17's and 18's. Will 18's raise the car any? I can't stand these cars in the hood I see with 24's...Its God awful!!! Reminds me of the days with the Toyota pickups with the 12" dayton spokes sticking out a half a foot from the car. Just as bad!!!
The only thing that matters is that this is your car, not anyone else's so if your happy with it than that is all you should care about.
