Damping is the function of the damper.
The damper the the olio-pneumatic strut sitting in the middle of your spring at the front, and between the frame & chassis at the rear. i.e. your bilsteins...
The are often referred to incorrectly (thanks to stupid Americans) as 'shock absorbers'. They don't absorb shock, they damp motion...
A shock is a force which is absorbed by the spring. The damper then controls the motion of the spring, to limit acceleration and prevent oscillation. Trust the shermans to confuse the issue!!
Just do a google search on 'damper' or (
) 'shock absorber' and read up on what they do and how they work. Not really complicated, just oil and gas being driven through various valves.
Your brake balance actually seems rather front heavy but it depends entirely on what calipers you have fitted and what effort is produced by the resulting front / rear pressure distribution... You may have relatively 'strong' rear calipers.
The best way to determine the best bias is to just have a play and see what happens. If you have ABS it's a doddle, you just start at 50/50 then brake hard from 60 mph to standstill and time the stop using a G-tech or similar. Increase the bias forward by 5% and repeat. You should get a minimum somewhere around 60/40 to 70/30 before your distances start to increase again. After you've got a nice graph of braking time vs bias, take the peak value and add 5%. You'll then do your 'seat of the pants' tuning to maximise braking vs stability into corners. You can often get a fair idea by braking hard in a straight line and gently steering in either direction to see how easy it is to unsettle the back. Strictly speaking there is no 'perfect' setting as different drivers have different preferences.
So, what discs and pads do you have fitted?
