However, larger diameter's will (slightly) reduce your acceleration but increase your overall top speed... Probably not enough to notice. If you do run 18's you'll probably have to run something like a 40 or 45 series tire, whereas the 17's you might be able to get away with a 50 series. Kinda helps keep some rubber on the sidewall.

Pretty much all of this has to do with your personal taste. But if you want an idea of what different types of wheels will look like on your car, click here. I believe that for the model year you will have to pick 1992, as that is the only year they have a MKIII Supra in the "Showroom". Once you have the car picked just click on a wheel manufacturer under the pic of the Supra, select a style, and the size and it'll show you what it'll look like.

wel thanks for the link it helped alot convincing me and 17 it will be
