Restoring suspension / ride quality on M6

[vroomvroomvroom]

Folks,

My (2nd hand) 2016 F12 M6 continues to be an absolute delight (after I had to drop in a new engine). It's been mostly perfect since there (except for me needing to redo the front rotors).

However, the ride has gotten a little rougher, and somewhat strangely, the sport+plus mode rides better on crappy bay area roads than the comfort mode.

My tech did a couple of cursory looks and thinks the suspension is still fine.

Do folks here have suggestions on specific things or settings I should ask him to look at? It's got <50K miles so I don't think there are major wear and tear issues ... but wondering if maybe getting the suspension fluid changed will help?

Haha 2014 M6 owner here😀. I’m also on my second engine.
Do you have comp or non-comp?
How many miles on the car ?

After I put my engine in it had a funny suspension as well. Turned out it was part of the break in process and some module for suspension had to re learn. Strange but once I cleared codes after break in the car was driving great !
