We finally have crowd sounds! I've also fine-tuned volumes of the brake markers because they sound so much louder than they need to.
I'll point it out here, and also on the main mod page, Adjusting volume of the engine with the car you're racing might be necessary, anything from 3 to 10. This might end up changing eventually but for now I've noticed many third party cars are crazy loud and require turning down to a desired/balanced level.
