I moved my plate up a bit because it was blocking the lower air intakes to radiator.
Position of plate now lines up better with the bumper, the plate intrudes less into the open air space.

That done, the cooling seems to be improved. Hopefully the aero is just a hair improved but I have no way to test it. Sorry, no pics of this mod yet.

I noticed most modern cars have no license plate bracket, just holes behind the license plate and the screws go thru the plate and right into the threaded holes. So if you want to move the plate you need to use a bracket which screws to two of the existing threaded holes. Then attach plate to the bracket. Harvest brackets from older cars at junkyards. Volvos used 'em through the mid '90's.
