The grille on the Leaf is pretty minimal as-is, but I noticed a while back that part of it is fake. So I decided to block off the outer parts and make it flush (or more flush, anyway) with the front bumper.
Grille with "fake" part to the left.
Posterboard mockup of partial block. Final version to be made from ABS.
This car is from California (San Francisco, if the previous owner's sat-nav addresses are to be believed), and though front license plates are a requirement there, one was never installed. I bought a super cheap bracket from Amazon and I'll be installing it soon. I'm thinking dead center, to help block part of the middle as well. Should leave plenty of air space on both sides. This bracket will allow me to mount it off to one side at a slight angle if I so choose also, if this blockage turns out to be too aggressive. I think it'll be fine.
Full mockup. Holy hell, LOOK at that panel gap around the charging door! That's pretty high on the list of stuff to fix.
Now I'm just wondering, stick with white, or paint it black?
