Thanks guys! I was a little torn between yellow or gold/bronze for the calipers (something like the G35 coupes had, and what Lexus is doing now with the F models), but William was willing to part ways with his yellow kit.
I really love these wheels. I was on the fence about going 19 (and aesthetically wish I had), but the 18's ride quality and added protection from taller tires made the choice pretty easy.
