I suspect he merely mount it on gap between the trunk lid and the rear quarter panel. In general that is a good location to mount a wing to the chassis but his wing position (relative to the chassis) will generate massive amount of down force. Given the leg is at 45 degree there will massive amount of leverage apply to the mounting location. IMO, probably too much for that mount location to handle without additional support.

I think you might be onto something, when I talked to the owner at the RS meet he told me he had calculated the load bearing force based on the amount of pizza that was stacked ontop of his trunk at the last track day. He said the approximate load on the wing with a safety factor of 2 should be approximately 70-80 pizzas or 110.4kg (1083.024N).
Someone once told me engineers make good assumptions are you in the industry v67gsr? Would love to hear more about your assumption and calculations on the load bearing force at 45 degree angle.
Do you think his setup is meant to handle the amount of pizzas he claims it can hold?
