Kuzma 4 Point owners - Do you use damping?

Hi folks,
I have a Lyra Delos mounted on a 4 Point on a Satbi Reference.

I find my left speaker woofer bouncing quite a bit more than the right speaker woofer (on the majority of flat LPs, not warped) due to subsonics, but the soundstage is well spread and vocals centered. Not that I can hear anything from the subsonics, but I find it unnerving looking at it. And I have no "subsonic-off" switch on my equipment.

I think my cartridge is mounted "precisely" as far as I could, but I have no test tool to check for Azimuth or anti-skate.

I cam curious if anyone uses the damping trough on the 4 Point arm. Will damping help?

All other advice are welcomed too.
Thank you.

PS: I used to be a Rega user, so it's fascinating that I have so many parameters to play with...
