No. I had a set on my e36m and no matter the damping it was bouncy. Again it was for a different car but don’t think it would matter.

If it feels bouncy because spring oscillations are being controlled, turn it up. If it's bouncy being too stiff, then you need to turn it down.

You have adjustable damping? Depends strongly on your spring rate, linear or progressive springs & ride height for what level of performance you want.

If you're looking to purchase, recommend you give Jay a call at Ground Control - he'll deliver just about anything you want.

If so, the answer is to replace the rear upper shock mount with Dinan rear shock mounts.
This will take away all of the bounce, hop, pogo, and slop of the rear end induced by the too soft BMW units.

I go into details about it here...
https://www.e90post.com/forums/showthread.php?t=1024256

These Dinan mounts are the best $100 I have ever spent on any car.
Monroe makes stiffer mounts for about 25 dollars. I haven't personally used those though.
Just get the Dinans though and enjoy! Thank me later. Lol.

Oh also be aware that, in addition to being a stiffer than the BMW mount, the Dinan also increases rear suspension travel quite a bit too. They truly tamed the ride motions in back AND ride smoother too. #win

Interesting... I had B6's on stock Msport springs on my old 06 330i and the rear still bounced on those until I changed out the mounts.

Glad the B8's are working for you.
