I think my wheels would look really good on your White Supra. It is just a matter of preference what wheel is the best. From a performance aspect, there a lot of competition wheels that are light and strong. Do some research to suit your driving style or usage and make the decision from there.
I personally prefer mine. They are reasonably light and come in the proper widths and offsets to maximize the space in the stock wheel wells. I run 18x9.5" 50mm offset with 265/35R18's front and 18x10.5" 55mm offset with 295/30R18's rear. This is with eibach springs and no suspension mods.
BTW The wheels are SSR GPO Decolte Evolutions and there in my sig.
