it more depends on your clearance angle, which is a function of ride height and how much vehicle extends beyond the wheels at the front or rear. 2" of ground...
I raced a tadpole trike with 3 inches of ground clearance two years ago. The front end of the body must have had an occasional scrape, but it overhung the...
