The skirts on the CRX are within a half inch of the sidewalls.On the pickup,I have about an inch clearance,and they are actually open at the bottom rear to clear the tire sidewall and also aspirate the wheel cavity a bit for brake cooling.Looking from the front,as the air see's them,They're kinda like a shingle,over-lapping the rocker panels behind the rear wheels,with an integral horizontal strake between skirt and rocker panel to "fix" the position of the trailing edge.A bit primitive but tufts showed clean flow all across the span.If you can find the Phil Knox photos,there is a shot of the CRX.I don't think we have a current shot of the truck with the deepened rear skirt(there is only one,[long story!]).
