So, Dick, IF the original intent of that rules was to allow the wacky rear suspension changes you guys are doing (and, as I said, I don't know that one way of the other) then yes, changing it is truly a rule change. But, if this is nothing but a clever loophole that's been exploited for 15 years, you should be prepared to have it closed in your face (and the rulesmakers should put ZERO weight on its cost effects and breadth.)

The problem with that perspective is that as you say the third link concept on solid axel cars has been prevalent for about 15 years. The ITAC takes into consideration during the classification process different suspension design and any adders for solid axel would of course be based on how they work in the current environment. That would have to be readdressed if a rule clarification was made that dramatically changed that type of designs effectiveness.

By the way sorry about your hackles. :P
