Their CF Engineer built racecars for NASCAR, Team Penske, racing legend Dan Gurney and various race teams.
Also, the designer, knows his !@#$ about aerodynamics. He designed the CF underbody of his 2005 black Gallardo, he contracts alot of his design ideas as well to consultant Boeing Aerospace engineers and he probably is the only tuner with two autoclave in his warehouse.

I still don't see how the CF doesn't melt off from the exhaust heat.

They certainly have a different concept than ASM. ASM runs vertical fits on the side diffusers to channel air back and leaves the center part open for cooling. They also run a diff and oil cooler with the front and rear diffusers.

From what I've read this is a "dry carbon" panel.
This is what I found on that term (
from another site - unrelated):

The manufacturing process to achieve an ideal dry carbon fiber performance product requires the carbon fiber weave to be “preimpregnated” with the ideal amount of graphite epoxy prior to the molding and curing processes. This differs from the wet carbon fiber process in which the epoxy is applied to the weave continually until the appropriate amount of surface area coverage and thickness is achieved to meet the strength and consistency requirements of the product design. The resulting product is so much lighter than wet carbon fiber because there is absolutely no excess epoxy, which accounts for the “dry” appearance of the finished dry carbon fiber component.

High temperature epoxy can go as high as 300 or slightly more in dry conditions and 250 in wet conditions as long as it has had a post cure cycle.

Okay, I see how maybe that belly pan contends with the heat if using a combination of reflective metal heat shielding, dry CF (
less epoxy) and use of high temperature epoxy.
I've just never seen this done before.
Seems out of reach technology wise for the backyard tinkerer.
