Do you still have your plastic tray setup or did you switch to a different material / setup. Also, have you noticed any mpg improvement, I'm curious since we both have Saturns.

When I finished this I was in the middle of a good run. Unfortunately things got really hectic at work since the start of February and I have been unable to sustain the "rut" I need to infer gains or losses. For instance, now I am commuting, which adds weight and compromises my driving style.

I would claim that a good wheel cover design can get you +.01 Cd :



PS - I like your wheel cover design and I agree that a flat wheel cover is not compatible with my design. I have been looking for *years* for a tray like the one I am using. I did a similar design to yours before my current one in this thread. While not impossible, you will find that a small hole for the valve stem will leave you vulnerable to having the cap fall *behind* the wheel cover when you take it off (@#%*^@#*%*&#). You can solve this with :

1 - A bigger hole so that you can get a better hold on the valve stem cap or ...

2 - A valve stem cap shaped like a nut. This will allow you to unscrew it with an appropriately-sized socket. The "trick" is to put a (flat coin-shaped) magnet inside the valve stem cap so that the cap stays "stuck" to the socket.

Kinda silly, I know, but it worked.
