Update:

I haven't had much time to work on the car, what with being back in school. But I wanted to get at least something done before this year's GGP. So, I thought I would try some air curtain ducts. I have the internal ducts from a Hyundai Ioniq, but rather than retrofit them I used them as a model for some (much easier to fabricate) external ducts. The Hyundai ducts are about the same size as these, ~30mm inlet, ~20mm outlet, ~150mm tall, and angled downward toward the outlet (that was a surprise). So, these are too.

Cardboard template:


Ducts in aluminum. I'm happy with how they turned out, considering I: a) have no experience working with aluminum, just tin and lead pipes (and some zinc repair); b) have no mandrels or brake.


On the car:






I don't know why the Ioniq's ducts are angled downwards, but I'm just copying for now. I'll take a close look at other air curtain ducts at the Chicago Auto Show next month to see if other manufacturers do the same.
