well i just looked back at my gasslog for my previous car... when i got it it had mudflaps that where just huge, after i took them off i saw about a 2-3 mpg improvement. but again they projected quite a bit beyond the sides of the wheels.

as for that corolla dam, it does look suspicious,but i don't think they'd have bothered to put it there if it did notting, it's not like anyone care or even knows these things are there or not so if they didn't work they leave them off and save on production costs... an uncle recently bought a new vw passat, and the dams on the font wheels also had an opening above them, with a duct to them from the front of the fairings... this was a very solid and deliberate setup.... perhaps break cooling...
