The undertray looks performant. The step is preferable to a slanted tray, IIRC.

What are the red fences supposed to do? Usually skirts are at the rocker, between the front and back tires.

Made it as far back as I could go but due to exhaust/rear beam etc it will be quite difficult to go further.
Good results though as at 23.9% throttle went from 90kmh to 95kmh on the same stretch(Sadly not a long stretch so could be bigger differences but NZ has alot of hills).
Good job on the undertray!

The fences were meant to capatilise on the area under the car by decreasing the distance and channeling air so it runs over that area rather than moving out the sides etc.

Im still doing more research on weather that would actually work but will keep it updated if I do any testing.

Thanks guys!

This looks fantastic! You might experiment with a small air dam; the step in the tray is probably developing a pressure increase in front of itself, and an air dam could mitigate that with reduced pressure behind. Honda does this on the current Clarity, which has a similar step under the engine/transmission and a full tray behind it:



Might be worth an experiment-- I don't think it will change drag much, but should reduce lift a little.
