Hi there. I have set up a vehicle using btRaycastVehicle. The chassis is very low slung, almost touching the road surface. The problem is the wheels seem to collide with the chassis shape and I end up with a flying vehicle because the wheels think the chassis is the ground. It makes for some very strange behaviour.

Is there a way to stop the wheels from ray casting against the chassis?

I'm sure this has been covered before, but my search skills are failing me (maybe I am using the wrong keywords).

Thanks everyone!
