I'm gonna try and post Kamm's 'templates' in a couple of weeks so everyone can see some his design evolution.
In 1955 he went from Stevens Institute down to Florida to consult on the design of a LeMans racer of Briggs Cunningham.
One of HOT ROD Magazine's road warriors was at Cunningham's at the same time and 'attended' Kamm's lecture on aerodynamics as he worked the clay.
Kamm was generally recommending a roofline of 10-degree slope,however when you see what he did for Cunningham you see that he broke his own 'rule.'
His last project was a Kamm-back modification to a 1960s DKW sedan which had a very conservative roofline and included his double,bifurcated,offset trailing edge roof fins.
I think he would say that the AZTEK roof was a little too fast and would have the vorticity that Darin has mentioned.
My guesses suck,but if you pinned me down,I'd think its Cd was in the neighborhood of 0.36.I would very much like to see a published figure.
