You should have sufficient airflow under the car hitting your tire and wheel on the inside, unless you have added deflectors or something else similar in front of them. Remember the air flow under the front part of your car is typically at about a 30 degree angle.

Someone asked about forced air brake cooling using ducts. These create constant drag as they constantly are ducting the air cooling the brakes whether they need it or not. I explain a way to use the brake light signal to turn on/off the ducts, so that they do not create drag when they are not needed. Apparently this is not welcome.
