An example of this would be the small retrofit wing on a 1st gen TT or deployable wing on a Boxster vs a large wing on DTM race car.
Replacing the plastic inserts with mesh may have actually increased the drag and destroyed the functionality of the vents as designed.

I don't think they are real/functional vents. If they were, you would probably be seeing pebbles/rocks fly through, but don't think there is an actual opening
