diffuser/mpg
with respect to mpg,the diffuser embodies the very rear portion of a complete belly pan,which begins its upsweep as underchassis components permit,rising vertically at no more than a 2.5-degree angle for attached flow.No vanes would be necessary,unless at the extreme outboard position,to form a rear wheel fairing as well as an undercar horizonatal stabilizer for center of pressure control(crosswind stability)as invented by Dr.Alberto Morelli.Vanes of any orientation other than parallel would probably see separation on their leeward side.Spanwise divergence between the rear wheel fairing/diffuser dams could sustain 7-8 degrees,well within the limit for a divergent nozzle in fluid mechanics.Again,the vertical component of the diffuser upsweep is limited to 2.5-degrees.---------- Not sexy,not racy,but it works.
