I was making a weekly drive all summer that involved a total 10,000ft climb and drop in one day, so no I don't feel like blocking my grill would be a good idea. However, on the whole trip I hardly every use my brakes. So maybe pizza panning the rims would work just fine.
You are 100% right, it's just a matter of what's needed for the conditions you're driving in. I think we all drive with very little brake use in our Leafs, also, so maximum cooling is not a big requirement.

Did you document your results at all? What type of vortex generator did you get? As I said in the video it's pretty much 100% theoretical and I have no good way to test except looking for extra dirt on my rear window. Placement in relation to the trailing edge of the car, size, pattern, etc all play a roll.

Was this you who did this mod? If so, where did you get your shark fin antenna and what model was it?
I searched Amazon and saw hundreds of different Shark Fin antenna's and was wondering what one to get.
My OEM rod antenna broke in a car wash and have been limping by with a 3" screw, but it doesn't look so hot. Basically all new cars now come with a shark antenna so I was thinking that might be the way to go.
I'm assuming XM works OK with these shark fin antennas, and how does FM work? It still works with my 3" screw but it's not as good at getting some FM channels as well as I remember the OEM rod antenna.
Yes that's me

I got the sharkfin off Amazon. I think I'm actually just going to remove it and leave the OEM antenna base all by itself with nothing screwed in. I pretty much only use Bluetooth audio anyway and the sharkfin is a) the wrong design for aero and b) larger frontal area than needed. I would offer to sell you my rubber ducky antenna but I am keeping all original parts for my Leaf so I can put to 100% stock to sell in the future.
