Does Aero Matter on Dirt?

I think if anyone actually enforced rules, a lot of the bodies out there would be illegal or at least the noses. I don't have a AKRA rulebook as I still need to get back up to Don's shop, but WKA (which most tracks still run around here for non-motor rules) a lot of those fancy noses don't meet the rules.

Anyways, my opinion on this is that the nose/body does more when you are 2nd on back and need to peek out to pass. Do you suddenly get tight or does it still rotate as you want? That is where I would concentrate my aero studies.

PS, all of the new sprint kart noses have wicker bills and it has been proven a gold cup (think dirt oval style) nose is faster than CIK bodywork.
