@BrentHasty I realise the leaf and it now resides in Finland but did you have plans/templates for the transparent kamm back parts? Id like to make one/two for my leafs

@Dala thanks for all the mods you are making, a great contribution.

I was also thinking of moving to a steel 15” rim with narrower Michelin energy saver tires. Reduce unsprung weight.

I like the skirt idea. Wonder if it could be done safely with something that didn’t require drilling into the body.

Will a 15 inch wheel fit over the front brakes?

Dala,

Do you know what temperature we could reasonably get up to with this kit installed? We regularly hit 38C where I live, but I also never QC. I have a 2011. Would a 24 kWh that only drives up to 60 miles at a time ever run into a problem?

What components might overheat as a result of the reduced airflow?

I've absent-mindedly left a grille block on in 80F temps with no problems. The first components to get unhappy would likely be the A/C system and the onboard charger.

Same here. With my 2013 Leaf, I would leave my painters tape fashioned grill block up for most of the year. Can't say I ever saw the battery having a warmth issue. It's wonderful in cold temps as you reduce the cold air into the cabin, and retain a bit more residual heat on the battery during hard driving.

Has anyone considered a small block on the bottom of the 2018-2019 grill. Think it would help much?

Do the reverse mud flaps really help much?

Hey Doug. What are reverse mud flaps.

Where you put the mudflaps on the front of the wheel well instead of the back.

An increase of 0.2 miles per kwh only means a boost of around 3 miles per charge.
But if it saves you from going into brick mode on the side of a busy dangerous road or gets you to a charger in turtle mode 1 time, it's totally worth it.

If you don't have mud flaps adding reverse mud flaps won't help much.
Just a mud flap deletion, if you have then will give a very slight range boost.
OEM mud flaps act like little air scoops that add drag. Turning that mud flap backwards, moving it to the forward side of the wheel thus using it to block air turns that aerodynamic liability into an asset.

The most economical thing you can do is take the mud flaps off if you have them and sell them on ebay. A new set of mud flaps is $125 and you have to buy the whole set.
So I bet there are people out there who have lost a mud flap and don't want to buy a whole set of 4 and would buy a used one.
