This is not a new rule it is in the current book. You can buy a new rule
book, as soon as they become available at the SCTA/BNI web site on line.

Evidently you missed Dan Warner's post on this subject. There is nothing in
the rule book outlawing A arm indipendant SUSPENTION. The proscribed design
is a solid mount like currently in use on the front of rear engined
dragsters in the NHRA. The rule was instituted after several failures one of
which I believe involved a fatality.

As several people on the list have pointed out in the past, on page 12 of
the current rule book there is a name and address to which you may
correspond regarding the rules or specific technical or safety questions.

Many special construction cars use indipendant suspention at all four
corners, you wont be pioneering anything new.

The above is all well and good Dave, but you need to address the thought
that you may be trying to solve a problem that dosen't exist for cars going
in a straight line.
