Thread: New shock absorbers for my Def

arent the Koni adjustables, only adjusting the rebound? That is the valving that contols the body/body roll....it wont change the bump valving which is controlling the un-sprung mass (axles etc)

I think this is what I was told

Yep, Koni road damper's adjustment only affects rebound, already mentioned in post number 4 and Koni's and roll addressed in posts 7 and 10

Low speed bump valving also affects body roll/transitions.

Basic rule of thumb with valving is bump controls the unsprung mass, rebound chassis stability but most race suspension engineers on cars these days, particularly on cars with downforce use low speed bump for roll/pitch/squat, as it seems do Bilstein in their HD 4WD shocks.

Ultimately anti-roll bars/springs/CofG control ultimate roll/lean angles, dampers alter the rate of roll, ie. how fast it happens but don't limit/change the ultimate roll angle (unless they limit droop, but that's another story)

But you would remember this from various conversations
