umm..... huh?
the twist is what gives it the spring rate regardless of where it's set,
and the only thing that page says is that if you add weight and then crank
up the bars to compensate the *effective* spring rate is increased. If
you have the same springs with the same weight in different rotational
positions the effective spring rate would only be changed by suspension
scrub radius changing how much leverage the tire contact patches have on
the A arms.
