Yes, instead of (already eternally past introduction) different rims front and rear, we rather need different left and right rims. If you are now asking whether I have had a drink, you better take a look at the rim above, which is mounted on both sides (!).

The necessity is obvious, because hardly a new presentation appears without a comment about the great aerodynamics of the rims, possibly with specific figures. The problem is, the car is only shown from one side during the explanation.

On the other side, of course, the same rims are mounted. But they turn the other way around. Can you imagine that a special aerodynamics can be achieved as an overall product? Does a car moving backwards have the same low drag as forwards?

So please, if the rims can really contribute so much to the streamlining, then please optimize only for one side and conversely transferred to the other side. Please note that the proportion of air for the brakes should also be calibrated reasonably precisely.

This also fits to the tires, of which very many have an asymmetrical profile and are bound to a certain running direction, e.g. because of this or because of other reasons. During assembly, the arrow on the rim should simply match the one on the tire. If one is already doing something, then please do it correctly.

Recently, the air is even been advertised, which is directed into the wheel arch below, does great things there and then even exits again at the back. In some sports cars it is even supposed to past the door, enter again in front of the rear wheel arch and achieve even more.

Enormous processes that positively influence aerodynamics are supposed to take place in the wheel arches themselves. However, you won't notice any of this at the already rather poor c_W values of real sports cars. It is more likely to be marketing inventions. That's why you could start with directional rims.
