Which is what people in the industry are up in arms about.

I think that is a furphy. The end plates are a flat piece of carbon fibre, they aren't magically making 'side force'. In normal cornering the car is basically at zero yaw angle, so as far as airflow is concerned still straight. Apart from body roll and front wheel angle it is no different, and insignificant to the rear wing.

Still a sponsor friendly size....

Parity based on race lap times to me is sporting parity, not technical parity. It's assuming teams, equipment, setups and drivers are all of equal quality.

Maybe losing the bottom edge will create more drag from less clean flow separation at the rear of the quarter panel, losing a bit of upper leading edge perhaps a bit less clean up of turbulent airflow but surely more appearing to do something.

Absent of proper testing lap times which lead to winning are an indicator of a discrepancy, at least when there were enough data points. If the Mustang was not dominating because the teams were still sorting it out, there wouldn't be any complaints of aero advantage?

My opinion is Supercars were too weak in allowing such a departure from the road car body shape. I would have dealt with the roof height problem by raising the belt Line slightly, and kept an authentic shape front and rear from there. It would mean a deeper front spoiler and side skirts (higher sills) which would be easier to make look good. If necessary for drag, a bonnet vent from the grille over the radiator could reduce the effective height of the front end.

Ideally Supercars should be driving the design of aero additions to the cars via their own staff. With the intention of being touring car racing, big downforce is not needed so elements could be pretty similar between cars. Do wind tunnel testing to validate the numbers, open access to data for the teams so the process can be trusted. Far better than the current secret-squirrel megabucks (or not in the case of the Nissan) development; the championship is about racing after all not aerodynamics which nobody really cares about and which can only be a distraction.

This could improve variety in the championship because it would reduce the input required from manufacturers to participate and thus the barrier to entry. More variety, more interest, more sponsors etc.
