But this is a National class so the 'formula' can change by changing the rules every year. If you are saying that weight alone can't compensate, no matter the quantity, ok.All other things being equal, a chassis with two seats is going to have an advantage over one with four - frontal area, aero "licked surface," impact of bluff rear surfaces on Cd, and center of gravity to name a few. The formula for setting spec weights doesn't take these variables into consideration, nor can it really be expected to in any repeatable, consistent way.
