Celica Forums General Discussion Exterior 17" Rims.

If I get a set of 17" Rims, Does it higher my car a little?

no

not at all sits at the same height

Here is just one of many calculators you can find. When I bought my GTS I was running the GT tires and wheels. That's just how it was. I now have 17" x 7" with 215 by 40 mm and it is a tad lower than stock 15's. You can't really tell by looking at the wheels and tires. Search around for a wheel or tire calculator if this one doesn't suit your needs.

actually if the overall wheel and tire diameter is bigger or smaller than the stock it may higher or lower it overall. chances are not by much

If your not gonna be lowering get 215/45/17 tires to fill in the wheel well area better.
