I've ran both staggered and square set up. I haven't really been able to tell the difference for I only track at least once a month "allowed by wife". Currently I'm running Te-37's Front 18x9.5 et 20 w/ Hankook RS3's 265/35/18 Rear 18x10.5 et 22 w/ Hankook RS3's 285/35/18 w/ KW Clubsports suspension. Be mindful what kind of wheels to get if later you decide to upgrade to a Big Brake Kit. some wheels will not fit a paticular BBK. I'm running Brembo's front 365 mm and rear 345 mm rotors. I really like my set up and it's a popular set up. Hope it helps narrow your search.
