Apex makes the exacted wheel to our car's size. Everyone else you have to go up to a 19 in order to get the off set's right. I love my Apex EC-7's. The Race Silver is not as bright as Hyper Silver so with all the black I have it makes the car pop out just right.
As far as Blue with Black wheels, I personally am not a big fan of that, great for racing the car, keeping the dirt down, and other utility uses, for show, go with the bling, that's my thing.
But that's just MHO - Its your car, make it look "Righteous" to you.
