I tried this as well. I ended up w/ something that "simulated" driving on a frozen lake bed --- a skating rink. But without too much more trouble, it could work. I think the challenging part is going to be modeling the suspension system. FWIW: I know that in motorsports people are using ADAMS to model the system dynamics.
