I've got aerospeed RSGT 19' wheels, The wheels are designed for every application. (ex.) My wheels have a 45mm ofset, These wheels are designed to were you can use the full turning radius w/out rubbing anything. Never have any problems.
If I had to do it again I would buy 17 with a beefy tire. Its just annoying to change them everytime I go to the track.
But the 19's look better. They fill up the huge fender well the celica has.
Hope this helps
If your concern is break wearing, check the weight of the wheels, (no fat chrome)
