I was about ready to agree with Bob (sorry) -- I always thought 18s were a little too much on a muscle car -- until I saw the comparison picture. I think you nailed it girl! Way to go!!
6pk2goDemon here ya go, I have the Boss 338 18's as well but I am not putting the 18x9.5's until I get more lift in the rear. Probably Firm GFeel or Hotchkis spings.
Duke, Thx for the PM and posting pics of your ride, it's beautiful! I love the early Cudas and yes, it looks like you'll need a bit more lift for the 9.5's. I'm not familiar with the springs you mention, but I'm sure you are. I have the 002, 003 MP springs.
