In lieu of having our own cars and wind tunnels, we are at the mercy of occasional published simulation work and word of mouth on these DF share percentages. 34% is the same figure mentioned previously in the RE article--maybe he was also involved in that sim. 33:33:33 is a reasonable assumption (front:mid:rear device DF share). We don’t know if the beam wings were counted as part of the floor or as part of the rear wing. We don’t know if the diffuser was counted as part of the rear aero generally, or as part the mid body aero. Note that while the floors in any era of these cars is the largest aero device by area, the front third of the ’22-type floors produce positive lift. While it may lose out on certain measurements of efficiency, a raked flat plane, generally speaking, produces negative lift across all of its surface.
Second guy on the internet expecting to see rake on these cars after yours truly, though I shall withhold judgement until I see the quality of his Colorful Freehand Drawings.
