As to the flared vs flush.You don't want want to add frontal area if you can keep from it.
The 1936 Jaray Adler had 'bulged' front skirts which added frontal area and they were only good for a 1% drag reduction.
The flush urethane flexible front skirts on the 1983 Probe-IV concept helped reduce drag 9%.

I was thinking along these lines when I fabricated my front wheel flares. A aerodynamically better shape that did not increase frontal area. They seem to work. I do need to do a coast down test sometime though.
