Good detail image.
For those unaware, just below the mechanic's finger with ring on it there's a stud with nut to secure, this being the method of ride height control and trim for setup. There's a second (hidden) opposite this one on backside of that coupling.
It's located on the pushrod taking load from wheel into "bellcrank" and all that entails in spring & damping actuation.
The dull grey block to right of that fixing is part of a "shimstack" that can be substituted or added to in changing the effective length of that pushrod to lift or drop the chassis relatively in dimension against the spring component. Fairly easy to do, accurate in just change of component with the fixing undone, to then be secured against new block dimension.
Edit:- to add, this can't ordinarily be seen in running config as it has an aero "shield" sleeve in carbon fibre covering it in plain sight, but each of the four pull/push rod usually have this as method to fine adjust each corner precisely.
