I feel we are in for a disappointing season.

seriously, do yourself a favor and make pilgrimage to the Weathertech USCC race next year.

They offer stunning views of these race cars in person and when you are there, you can see that there is a lot of air management going on inside the car. The outgoing Z4 GTLM and E92 M3 GT ALMS race cars used air ducts inside the car to manage the air flow for critical cooling function. The rest of the air is actually passed through the car:













Here's more photos of the Z4 GTLM, GTE and GTD race cars that shows the air flow management. Note the ducts pushes air over the car.
..and yes, that's a P65B44 V8 under there.
