You will laugh but I was relatively new to BMWs when I got my M2 Comp 2 years ago. I did not know for 6 months that you can "twist" (pushing upward on the front of the seat button and downwards on the rear of the seat button simultaneously) the seat adjustment button. Once my detailer showed me this (punching myself in the face repeatedly) seat comfort got better exponentially.

Damn, just re-read your post, I don't know if the Carbon Seats are adjustable in that fashion.
