I'm sorry I havn't been visiting this site in a spell. Figured you needed an update seeing the coroplast bellypan went thru a rough year. First, I removed it, mostly because last winters snow fall was 2 feet, and I was scraping the pan on more than several occations in order to get by.
The coro Hubcasps became quite brittle too, plus spinning my tires in deap snow didn't help much. I removed them several months ago.
I first removed the rear pan section soon after installing. I discovering it rode too low at the rear axles which was creating drag. I drove around for many months before winter with just the front section on and yes, I do remember it being a little quieter inside, and I'm sure there was some mpg gain.
After fiddling with interior mirror options in an effort to eliminate side mirror drag, I opted to re-install my drivers side mirror and this works for me. (The 4 section interior mirror was inches from my head!)
With the onset of summer I removed my plex air vent to keep things cool. My tires are practically bald after running them @ 45 psi, and the ride is rough, I did feel I was getting my best gain in mpg from running them that high, but by doing that I wonder if I hastened there life expectancy.
I'm back to my old habits now, driving fast as usual and not keeping up with the expensive oils etc. But I still chech my mileage and I'm happy averaging 45 mpg.
Not too many cars can do that, with one battery
