Anyone care to comment on what would be a suitable design clearance between chassis and road at full suspension bump travel for a car to be used on road and track.
For example, if a car had 100 mm of ground clearance, and a suspension travel of 60 mm in bump from ride height, the chassis would be 40 mm from the ground at full bump. I am talking here purely of the damper travel, spring rate does not come into it at this stage.
I understand that this clearance will vary depending on the actual profile of the road being driven on. I see some cars do "bottom" in certain circumstances, and you see people winding up static ride height or spring rate to try to prevent this, but in the case of a clean sheet design it would seem incorrect to design so that the clearance would be 0 mm.
