hi chris,
magstars have the same stud pattern as our rostyles, minilites, standard steel wheel. the magnun 500's have the slightly different stud pattern. i have a set of magstars temporarily on my NADA, well two on one side and a set of new S trims on the other. i am waiting for my panels to come back from the painters, i will then make my mind up if i want the S trims or the magstars on it.
