aside from the fact that it'd be cooler and u'd appreciate them more if YOU bought them...try searching the garage pics up top on the home page, lotta good stuff to see...if you don't see anything refresh and look at some more, .
edit: i forgot...17s or 18s on a 4th gen look best imo, and they fit the best. i don't think i've seen anyone with 19s or bigger on here, so ya...that'd be stupid anyway, lol.
16in rota slip streams!!! mmmmmmm. no 18's. 18's are gay. 17in max. if u get 17in with low pro's it will be the same diameter as stock. so u'll have room to lower it. bigger rims means less rotation and more work for your car. well unless they are lightweight. i believe the stock si rims are 22lbs +tires each. but i could be wrong. anyway. read sport compact this months issue. they talk about the truths and myths about cars and bolt on's and one of the things is that bigger rims are bad. so yeah. hoped that helped.
