I hard mounted the wheel and peddles with M6 roofing bolts (they have a bigger pan head) and 6mm penny washers , It only took an hour or so to do minor adjustments as the VR3 rigs are set up for the G25/G27 .
The rig is rock solid and is more than capable of accommodating the T500 . I read at the Vision racer forum and after speaking to Jeff (i think ) at Vision racer that they felt it may be an issue with the height with the wheel in relation to your seating position , But in my opinion the Logitech positioning wasn't to my liking any way and felt to low . (Go kart like) . With the Much bigger T500 it raised it up a bit and i loved it straight away (More GT like). .
Also i have added a Buttkicker under the seat which if you are looking to spend this much on these items is worth going the extra little mile .
Hope this helps and if you need any more info give us a shout .
