Bad news Gareth. The Fanatec wheel won't go on either the Logitec or MS mount for the Wheel Stand Pro. Understandable as they make a competing product. I need the table clamp gor work as it's not ideal on a desk with a metal bar at the front.
Paul, if you are serious about your 360 racing games then the Fanatec is the best you'll get right now. I do think you have to get the CS pedals as the basic ones aren't great, and not a patch on the Logitec ones. Price wise it's a hell of a lot due to the MS license costs, which makes it look overpriced.
I'd be tempted to ditch my existing wheels and replace them with just the one though.
The MS wheel is great for the money, and the G27 is superb, but the Turbo S with CS pedals is the daddy, but is overpriced compared to the rest if their wheels, but as I said, that's purely down to the license fee.
