Here's my set-up. Pedals in rally position and angled down, with realistic braking mod installed. Obutto pedal plate at its lowest incline (I still get a bit of slipping, so I'm going to mount the pedals with industrial velcro strips). Wheel is attached to plate via supplied clamp with no slipping or movement thus far. Buttkicker Gamer 2 attaches perfectly to the rear support rail.
You can't see it in the picture, but I have the small receiver for a wireless Pioneer surround sound headset mounted to the bottom of the monitor stand just above the pedals; the Gamer 2 amplifier is mounted via a small bracket to the chair rail -- and run through the headphones in jack on the headphone receiver.
The Playstation Eye camera works, but only in Arcade mode, unfortunately.
Good solid rig, and fits the wheel and pedals very well.
How are you liking the pedals in rally mode? I think you're the only one I've seen running that setup.
Also please tell us how it compares to F1 style if there is even a difference.
