With an ET40 for the 9.5" wheels, you DO need to roll the fenders! I asked this giy on BFC with the staggered setup, he's got a major tilt cuz it rubs. Last i recall is him waiting to roll the rear fenders. I just cannot find the thread!!! Oh, and why they look good only staggered? Cuz the CSL rims look hot largely because of the concavity in the wider rear wheels, otherwise, @ 8.5" all around you'll have regular BBS-style wheels with flat faces.
