i've always had the same thoughts. the rear is the only bottom part uncovered and probably causes much aerodynamics disruption.

That open area is for the engine heat to exit. Pulled in from top and pushed out thru bottom.

Well The 991 cups are certainly running a diffuser and yes think about all the lift that’s got to be occurring there!Apparently the 992.1 gt3 has a diffuser and it’s super quick at The Nurburgring!

I never thought the 911 Cup had a diffuser. The R's have a diffuser but I've never seen one on the cup cars.

Definitely a part that seems to be missing visually, even on the 7;1

Assuming one could fit the 991 R rear diffuser do you think you’d end up with terminal understeer?

I definitely want a large rear diffuser and a way to extend the 7.2 GT3 uprights. A much bigger splitter as well. Aero is wide open in NASA Time Trials for my class.
