Hi.
W163, ML320. Installed 20mm Spacers on front, and it had improved look significantly.
It run without an issue for a year, now planning to install rear ones. Just for look.
But i think its effects (good or bad) on the car is more than a look
Theoretically spacers would increase the load on suspension system due to Law of the lever. (So faster wear and tear of suspension system)
I wonder how it would affect body roll (and rollover)
It softens the suspension system (bad for body roll control) but also reduce center of gravity. (good for body control)
I am not good at physics as many of you. i think here we should make distinction about "roll at mild weight transfers" and "rollover at extreme weight transfers".
Because for cars with higher center of gravity, with stiff suspension can have almost up to 100% roll prevention at lower weight transfers , but at extreme maneuvers or collision, they will rollover even with infinitely stiff sway bars and springs.
So does this mean lowering center of gravity have much more important role than stiffening the suspension in terms of preventing rollover ?
Surely, my 20mm spacers are too small to have considerable effect. Just i wondered the physics of it
So given the spacer with enough thickness, can we say body roll rate at mild weight transfer will increase but rollover chance will be reduced ?
Regards.
i found test videos, not sure if this is credible test.
