Every gnose I see, the airdam is so low I'd worry about scraping it on driveways and such into parking lots. Moreover, I rather like the front clearance the car has stock. However, I'm pretty sure the front fender flares go down far enough that you can't really adapt them without having an airdam lower to the ground.
In general, every imsa-flared Z I've seen seems like if they drove over a soda can they'd ding their airdam on it... so really, ride height with the flares is a concern to me. Have you guys seen any without such a low front clearance? I don't want a crazy high center of gravity either, though... Meh.
