wow...the definition of a genius is someone who can explain something very complicated and make it easy to understand.

You run the gold standard of youtube channels. Well-presented knowledge and demonstrable experience, no fluff, no annoying advertisements, no music, and great audience engagement. Thank you.

Thank you. I was trying to build aero parts for my Integra Type R. So helpful and informative.

It would be nice to see that graph of ride height / speed for the car without the undertray fitted, as comparison.

Sir you are a Gem.

Hi Julian,

Thanks good video. I have to get under my car in a few days before I'm trying to figure out how to attach the underbody flat floor. I have a 6mm sheet of alumalite I'll use.

great content, would be great if you could do aero videos on a s2000, very popular track car with terrible factory aero.

Just curious what the weight of your rear panel with steel bars weighs? I'm still working on my middle panels using T6061 .063 flat sheets with cutout in the middle for exhaust. Just looking for the stiffest, lightest material I can get my hands on. Love your videos. Using them now in building my panels

To your knowledge, is it true that if the undertray bends slightly down convex/concave at the front wheel section the lift will be reduced even more. Do you have a video on undertray bends at front end or anywhere else???

Arrm...is there a particular reason on why you have a negative rake on that car...as far as I can tell from your ride height graph?

Don't you need a before and after suspension height to see what the under panels actually did?

How do you effectively do this on a vehicle with a live rear axle?

What happens to standing water??
