actuallt i think 17 and 18 are a bit drastic as many here have stated already. They , to me, take away from the total sportyness and good look of the car, its all about the wheel also i fdo kno and respect that, i have upgraded my wheels before to 16's wiff 225 tires all around but then choose to put the factory wheels back on my 96 Integra Type r and just upgraded the tires to 215's. I was much happier altho the 16 werent really bad but i like the factory set better with upgraded tires.
