I'm definitely pulling at least the rears off then, if not all of them
Update:
I really wanna say my MPG has increased since installing the rear wheel skirts. Yesterday i got the best f/e i've ever gotten on my trip to school pulling into the lot - 48.5 MPG
. When i first got off the pike coming to the light after the toll booths, i saw over 50, then i had some stop and go driving. I've never seen it that high before in my life
. The best i've seen before the skirts was 47.5 pulling into the lot. Granted i could have had a huge tail wind yesterday, but when i got out of my car it was calm. I also got great f/e on the way back home, even in the rain.
Couldn't really tell today because it was about 15-20° colder, but still got 45.7 MPG. I did get some awesome f/e on the way home after putting on a small upper grill block in my school parking lot though before i left
