i have an 04 coupe, dropped on tein s-techs with ings+1 kit... i plan on getting either gt-c's or sf challenge...

will this setup work for my car without having to roll fenders, and will i also be able to fit a BBK for my front and rear?

19x9.5 +28f and 19x10.5 +23 rear

 

You'll have to roll your fenders in the rear whether you choose 275's or 285's, its a very easy process that can be done in an hour with a pvc pipe and heat gun/hair dryer.

BBK fitment is determined by the pad type, not so much the offset.
