+1 on that.i think 20s look good. most of them.
i think the important consideration is whether or not the rims are sport type or compton baller type.
i almost gaurantee that most of us will hate some 20" giovanna rims on a supra but will like and/or tolerate 20" volk te37.
some killer race car 20" rims would look jaw droppingly good at night downtown.
Supra is not a sports car. It is a grand touring/gt car. Real sports car only have 2 seats20"s = pimpmobile
Supra = timeless sports car
20"s + Supra = Fail
Simply put, these cars aren't built or meant for 20" wheels.
