Thanks again for the feedback everyone! please keep in mind this is just the first version of the prototype 3dprint, many design details are still to be fine tuned and we'll keep you all posted for updates. Stay tuned!

"The addition of the vertical ‘fences’ to a diffuser help to optimise the diffusers efficiency by ensuring that the air is drawn only from the underbody and does not spill in from the upper body surfaces."

Doesn't look like there's any airflow thru the vertical fins... the front of the bottom plate appears to prevent full flow of air thru the fins.. being one of the reasons for the diffuser to speed up the air to reduce drag along with creating down force.

what else changed in those models? Airflow going into the car, over the hoodline, etc all changed. I find it hard to believe the rear diffuser created a thicker laminar sublayer. It almost looks like you're using different fluid or, I'm guessing, different velocity in your CFD modeling.

thanks for your work on this
My 2016 Z07 is used almost exclusively as a track car and I regularly exceed 100 mph at the track. I am interested in this more from a functional point of view, wondering if it will help with downforce or if its mainly for looks. Let me know
