How about a simple amendment to the ground clearance rule:
"The minimum ground clearance is to be judged by the cars ability to roll over a 2x2."
This is a fast and easy way to verify durring inspection and makes it easy to test durring construction.

Perfect, it's super clear! Just wait until teams push the issue by using Birch....

Maybe not so clear -- is that a 2 x2 straight for the lumber yard that measures 1 1/2 X 1 1/2 or a piece of milled stock 2 X 2. It is still a good idea.

Yes, a milled 2x2 measuring out at 1 1/2"
We constantly have trouble with this rule durring races.

"Clearance between the vehicles lowest point and the ground must exceed the height of the tires sidewalls to prevent the vehicle from sliding on the ground in the event of failure of any or all of the tires."
It kind of depends on what tires the cars are running doesn't it? If you use the 2x2 and a car shows up with 700's, they would be "Too low" by your gauge, but technically in spec.
Maybe a series of gauge blocks based on the different tires available...? Hey, I'm new here and just trying to contribute. Devils advocate if you will.

Basically they want to throw out the above statement and put in the 2 x 2 rule.

If the 2 X 2 rule is adopted the car with 700s would out of spec because it is a new specification.

Basicly, yes. I am trying to have a simple enforcable rule that will be easy to enforce. Complicated rules tend to be ignored by both the builders and the officials.

Unfortionatly, the sidewall of the tire is only one consideration. A car with no nose or tail with 1" sidewall tires will require 1" of ground clearance. The same car with a 4' nose may require 3" of ground clearance. If it has a flat the nose will lower and rub on the ground. Even more clearance would be needed if it had 2 flats. Less needed if it has 3 flats. It is very complicated and almost impossible to enforce durring inspection. It also changes durring the race if the cars frame starts to bend.
