Noise from rear?

Hey guys,

For the last year or 2 ive had a noise from the rear happen when going over bumps, ( speeds do not matter, it can be at 20mph or 75mph )

The dealership cant seem to figure it out and im hoping to get some feedback here if its normal or if anyone has experience with this issue,
the rear shocks have been replaced by bmw and after that they told me its just a normal noise and acceptable by BMW.

It sounds like a compression noise while going over the bumps like a PSHHHH sound if that makes sense.

Wondering if anyone has some feedback or what it could be? anyone experience the same thing at all? maybe bushings if they will make a noise like that?

I had clubsports on my old f82 m4 and never had this issue.

Thanks!

Yep, normal on mine since the first day of ownership. It's awesome... That and the friction sound of the pads connecting with the discs when rolling to a slow stop. Because the GTS is lacking a back seat, sound deadening. Let's everything in.

Another reminder you're not in a normal car, recommended -- install a 6 pt harness and at certain rpm the exhaust vibration transfers through the cage, down the belts into your shoulders & chest.

Yeah, I've heard it from day one -- took ownership @ 800 miles. Specifically with compression over bumps, just as you describe it. FWIW, hear the same w/ compression on mountain bike suspensions.

It didnt start making it until about a year, so when a new noise popped up I wasn't happy.

If its normal its fine, but because it wasn't there before it concerned me.

Yup, mine makes the same noises, including the CCB grinding noise when semi-coasting to a stop with light pedal pressure. Can't hear the fronts, but the rear noises come through pretty loud and clear when not under throttle.

Understandable. Fair enough. Enjoy.

I have a noise but....

I have a noise... but I believe it's a stone or pebble not stone related. I'm sure this is nor the post for this but it's still a pain in the rear. It's "only" scrapes when I turn the wheel to the right in a curve or make a hard turn. It is coming from the left rear wheel.

After initially hearing it I pulled over and pulled the rotor with a slight tug yesterday and heard a stone release... then the scraping continued. Very weird.

Terrible...
