i jst changed my gearbox mount on my r32 gtr to a nismo one as the old one was worn, so much that the new one raised the gearbox a couple of centimetres higher than where it was sitting before, since the new install the car has been a bit funny, when your driving it is not as smooth as before ,ie feels like the whole care is vibrating more, and the cabin noise it higher from the engine running, also the turbos whistle on boost, and they didnt before,whats happened?
