Is your suspension stock? If yes, square is the way to go because the front camber adjustment range on the stock suspension isn't sufficient and you'll be eating up the outer edge of your front tires.
Mine are actually 18 x 10 ET 25 square.

Take off 275/35/18 grand am (hoosier/continental) tires are awesome. Also have used 265/35 hankook rs 3. Both work with no rubbing on stock car. I do also have camber plates but those were added after both tires were tried. I am very happy with square setup.
