Re the addition to the rules:-
F1) There has been a request that we look at reducing the minimum tyre diameter and minimum rear ground clearance in Formula One. This is to enable extended use of tyres. I.E. They can cycle through Can-Am then F1 then Saloon. Dimensions published in the F1 rules.
Saloon) The new advisory heights for saloon bodies now published in the Saloon rules.
Sporting rules) A new paragraph added confirming rule change procedure and voting rights.
