No idea. Some people have mentioned in other threads that it's probably a poor idea to open them arbitrarily, as you'll likely just gain wind resistance for nothing. RCZ is looking at making some ducting to open them and route the air to cool the front brakes, which might be worth it.
With an otherwise stock config, all it's going to do is open up more airflow into the radiator area, and off to the sides at that, so not very effective. There's no open path from them towards the brakes on the stock car, some things will have to be cut or moved to make room.
