David,
You may want to consider the SSR GPO Decolte Evolutions. They come in the right sizes and offsets for out car and several people (including myself) use them on the Supra. I would recommend the 18x9.5" 50mm offset with a 265/35R18 front and 18x10.5" 55mm offset with a 295/30R18 (or 285/30R18) rear. This can be done with no modifications to the car. These wheel can be had for about $650ea. There is a picture of this setup in my sig. You could also run a 275 on a 10" wheel in the front and a 295 on a 11" wheel in the rear with very little mods with this same SSR.
Later, Steve
