75 out of 100
I gave this on a go using a 5.1 surround Logitech Z960 accompanied by using software eq adjustments to get it sounding as realistic as possible.
Positives:
Great cockpit sound immersion. The engine sounds and transmission whines, sound like the real thing. It was hard to decide whether to use this one or stick to the original sound files which comes up pretty good when using software eq adjustments. This sound mod is worth the download and install. Cockpit sounds are realistic and convincing at lower speeds. Other critical sounds like kerb rumble and shifting were kept present and adequate.
Negatives:
While the sound file and level were excellent, it fails to maintain the distinct V8 supercar transmission whine at higher speeds. That whine doesn't get drowned out at higher speeds when I compared it to live onboards. Using the in-game sliders dis not fix this anomaly. This is the only negative.
Thanks for the effort in making this mod. It was fun to use but I really like hearing the whine at higher speeds because it makes me want to push more. If this was available it would beat the original or at least make it a damn hard choice.
