I am trying to decide what to block. A close inspection of upper and lower grilles reveals that both seem to have an equally good shot at the radiator. Here is the rad with the hood open:
A lower grill block would certainly be easier. I wonder if an angled upper block would give more improvement than a full lower block. I am thinking of doing a full upper block out of a nice piece of black plexiglass that I have (the bit leftover from the rear battery pack cover in the eBooger) and a partial lower block.
The fog lights also need aero help.

Remember to see how close your current tires are to any hard suspension parts.
remember 25.46 (current) - 28.00 = 2.44 inchs TOTAL.
2.44 / 2 = 1.22"
1.22" is how much taller the newtire is measured from the top of the old tire

I edited my first post to show that I run the summer tires at 45 psi and winter tires at 40 psi.
I doubt that taller tires would cause rubbage, but I will have to take a closer look. Thanks for the feedback on your "increasing tire size" experience.
