The rear mud flaps are still in place. I needed something to support the rear wheel strakes on the front end. The inside part of the rear wheel strake is still open...so air will still turbulate between the rear strake and the rear skirts. I'll have to button that up at some point and see what differences it will make down the road. During my 35mpg run (May 2011), I didn't have any rear strakes at that time...but I did have a rear diffuser extension and rear skirts.
I'll have to snap a few piccies when I git the rear end back up on the ramps and it's not raining.
Besides the higher prices fer gas from last year, differences this year were:
pulled the top of the back end of the aero cap in tighter by 12" which added back in the side slopes from my 35mpg run
added rear wheel strakes (last year's drive had none)
added full rear wheel skirts (last year's drive had none)
blocked the lower air dam vents (last year's drive had a air dam mustache fer the first half of the drive)
improved the cab-to-cap gap cover (last year's drive gap cover didn't work out very well and I had to resort to tape.
2 extra passengers along with their luggage/stuff (about 350lbs)
multiple extra stops fer passengers
cleaned the catalytic converter
I might have to experiment with just the upper rear wheel skirt (wheel fairing?) instead of the full skirt setup and see how that turns out.
