is that a custom finish offered by volk on those wheels? doesnt look like their regular mercury silver

 

I also may just go with 18's, but as much as i have tried to find out searching on post here i am confused.

if i go with 18x8.5's in the front and 18x9.5's or 10s on the rear what are my tire choices and offsets i need.

i came up with 245/35 for front and 275 or 285/30 for rear

if i get 18's i will prob lower it some also. looking at some tien coilovers.
