Stock suspension, lots of ground clearance. I see the Miata, a Del Sol, the Spec V, several other cars in those pics that should have similar or lower ground clearance and suspension travel. My two worries are running off course and hitting something or banging up the suspension on a rough surface, but the track seems open and smooth enough in those pics, and it should be smoother this time around. It looks like a lot of fun- I'm going to think about it for a day or two then probably sign up.
