Roadnoise Immersion Mod v1.0 by Predrag Drobac (aka SimHead on Youtube).
Since there is no sfx files to fine adjust wind noise at higher speed to add immersion and sense of speed, I made completely new roadnoise_in.wav sample, and tested it ingame for 2 days to be sure it is just right. It adds windrush, tire and cockpit rattle noise, jut like in the real cars.
You can hear the mod in action in the following video:
Additional info and how to install is included with the mod.
Cheers and enjoy the immersion.
