Anti roll measurement

I have a theory but that’s all (or maybe it’s just a hypothesis) but I was talking with my bother about anti roll bars and he thinks it’s a measurement of the diameter of the bar but to me that makes no sense (and I know if you have a thicker bar the stiffergigadythe car) what I mean is the numbers…and I was hoping that someone could confirm this but what if the thing you are changing is a ratio so for example 25.06 whick would be 25kg to every .06cm the only thing weird to that is how come the second part (the numbers after the “.”) Get bigger shouldn’t they get smaller??? And if it is just thickness why can’t you have just 25.00??? Its either .01 .07ext.

Idk what do you guys think

You can have ARBs at xx.00 by simply going to the Min/Max and then move to wherever you’d like. Example 1.00/40.00 (Min/Max).

.

It’s weird. I wish ARBs would automatically round to 1 place or drop the 100th place entirely. Springs bother me more, because only some cars can land on a .0 or .5.

The ARB numbers are just a scale for stiffness, from 1 to 40.

i always use formula to calculate ARB, spring
(Max-Min)xW%+Min this is the formula to cal springs, ARB, etc,. works really good
