The rear screw on the back of the 997 GT3RS, should not be that loose. It needs to be snug to limit chatter,  with a small amount of body float.   Thank you for the video.

Ah ok, makes sense, it still ran quite well, the cars are all packed up now for the courier but hopefully the next hope can nip the screw up a bit if it is not as it should be .
