Nice demo but I have a small crack in left audio when the car accelerate on a Vampire Firebird V4 with last core and OS3.1
It was cracking like overdrive in volume on first version, so I lowered the volume of the sample file and now V4SA core 10000 has clean audio. you can try edit audio file with Wavebox and lower the volume level more...
Thankyou i will try that as soon as i come back home.
