[V8]

Picked up my M6 coupe 2 days ago and noticing a couple of noises.

I hear a high pitched squeaking when I go over bumps. Seems to happen most of the time. Not crazy loud but noticeable to me and my OCD!

I remember hearing about this on the F10 M5, seeing as the chassis shares identical components. With them I think it was the rear coilover springs.

Anyone else noticed this? What was the soltuion for F10 M5 owners? Is it fixable or tough luck?
