The rear upper and lower inserts are used to fine-tune rear roll center setting.
The rear upper insert has 4 positions: TopOuter, TopInner, BottomOuter, BottomInner.
The rear lower insert has 2 positions: Top, Bottom.
By setting various combinations of the inserts, you can raise or lower your rear roll center.
When setting the rear upper inserts to an 'outer' position, you must shorten the upper arm length. This will give more camber change during body roll.
The DRS arm (dynamic rear steering) inner pivot point can be altered to match the rear lower insert setting, and will also have a range of adjustment as well.
At the front of the car, you adjust the front roll center setting by moving the upper arm mount up or down. This is done by putting shims under and above the arm mount.
