I have noticed that 3 people have downloaded the S2 car engine soundpack, and not the S1 and Demo soundpacks. Just to make it clear, the S2 soundpack only contains cars released as S2 content. This means for cars like XRT for example, you will need to download the S1 soundpack as the XRT is S1 content. For the FBM, XFG and XRG you will need to download the demo soundpack as these are examples of demo content. Do not just download the S2 soundpack if you have S2, as you will not get sounds for all cars!
