AST diffuser angle

https://ecomodder.com/forum/showthre...tml#post116392a) The images may not have been of sufficient clarity.
b) The diffuser is actually 2.8-degrees upsweep, beginning at 252mm,before the rear wheels.
c) The lower profile indicates for the bottom of the wheel fairing package, below the actual body. I tried to shade them, to provide some visual contrast to set them off from the main body. Sorry!
d) The belly pan at the nose is level, at 252mm ground clearance, however the front wheel fairing bottoms are 'LOW' and follow the front overhang at the SAE 16-degrees 'approach angle, sloping up from the face of the front tires.
Wheel fairings between the axles follow the SAE 10-degree breakover angles. According to the SAE, none of the bottoms of the wheel fairings would experience a ground strike. The lower extremities of the fairings would be level with the bottom of the wheel rims, respecting California State Law. Only the tire sidewalls would project below that level.
I apologize for the lack of clarity. Sunlight managed to degrade the ink.
The von Mises reflection of the rear upper body was a concession to room for taillights and a license plate.

The CFD is very interesting. Thanks so much!
