So, I have decided to revise my rear pan and see if I can make it a little more efficient. I have a couple of questions though. First, my rear bumper cover is quite rounded at the bottom. Might there be some benefit in extending the pan past the bottom edge of the bumper cover? I can easily go 3" without going past the bumper. Is that short distance likely to help enough to notice? Second, is it worthwhile building strakes on the outside edges? I was thinking of putting a couple in line with the inside edges of the tires.
