其实就是前后侧倾刚度分配的问题，我猜这篇文章默认车前后轴荷分配是1.38:1，没有横向稳定杆喽，要不然这些结论都是错的。
稳态过弯时车轮的载荷转移主要看前后悬架侧倾刚度，而如果没有横向稳定杆的话就看弹簧了，但弹簧压缩量跟车轮跳动量之比一般还不是一比一，有可能前后悬架都还不一样，所以弹簧刚度并不等于悬架线刚度，按照此文章说的来改车就更不对了。
我看的书上一般的建议是，让前悬架的侧倾刚度比它分担的轴荷百分比多5%，比如，前后轴荷比是45:55，那侧倾刚度比就是50:50，这样车只有轻微的不足转向。然后把这个当成baseline，通过试车感受侧倾刚度该往哪边调。

: And true enough .............................. After some test drive the rear becomes much less bumpy, in fact observing rear passengers shows no bounce off the seat condition anymore. The rear of the car also feels much more in contact with the ground and not bouncing off the road. Especially during turning, it does not jump lane anymore.
