Same here although not as drastic performance wise as your setup I decided to stay with 19s even though I prefer how 20s look. Either way cf5vs are not offered on 20s so that made it all that much easier for me. I am sure the your car is going to look great and a 45 tire will just make it look all that much more aggressive and muscular.Yup the black graphite color looks amazing to me from pics I have seen of other cars. I think you made a great choice.
My F14's are 19x9.5 deep concave front and 18x11 deep concave on the rears. I am going with a drag radial tire with a larger sidewall on the rear. Probably a 305/45-18 NT05R. This is more of a function over form setup but I am betting it will still look killer on the streets. My car is not my daily driver anyway. We shall see!
