Not sure of what I did!
 

:confused:I just purchased a set of 18x9 DD Black bullitts and 255-45-18 Sumitomo's from American Muscle. Will my wheel set-up be appropiate and look muscular enough? Will the deep dish look accomplish that thought? I have not dropped my car yet.

i have 245's i think on my 17x9's... they seem to fit right and look right. dont think you would have any problems but most people reccommend 275's

What model car? 99-04?

I'd be putting a 275 width tire on a 9inch wide rim. what year is your car?

very important question, since the 05+ mustangs wear a 255 on an 18x9

Sorry!
 

I forgot to mention that my Mustang is a 05 GT Prem. Mineral Grey auto just in case my wife wants to drive it. I originally thought about running 18x9 w/sumi's 255-45-18 in front and 18x10 w/275-40-18 in back all deep dish.But because of tire rotation, I chose 18x9's all around bought from American Muscle.What do you guy's think? Will this set-up look good and not cause any problems in the future.I am thinking of dropping my ride down 1inch in the future. Maybe! depend's on how the car look's after mounting. Thanks!

You'll want to lower it anyway... an 18" wheel is almost small on 05+ cars. 18's will look proper. Guess you should'a asked these questions before you made a purchase huh.

i keep hearing that i should use eibach pro-sport lowering spring's with my 18's dd bullet wheels on my 05 gt mustang. would my ride be ok with-out any other items meaning camber plates etc. etc.?

There's a chance you will need new C&Cs
