Could we get a picture in here?

It should be stated more clear that it is the difference between roll stiffness of front and rear axes which affects the weight transfer between the 4 wheels.

Moreover, the total weight on the two right wheels (and the total for two left wheels) is completely determined from statical considerations, thus does not depend on stiffness of the parts of suspension. Similar argument works for weight on the front axis vs weight on the rear axis. In particular, the explanation of effect of roll stiffness on over/understeer is not only unclear, but completely bogus. (In fact, it is slightly better [by being unclear ;-] than the [explicit] nonsense explanation in the external link.)

One expects that one needs more detailed consideration of distribution of weight between four wheels, and the fine effects of these distributions on "some particular angles" of these wheels to relate under/oversteer to roll stiffness. The effect cannot be as direct as in (hinted by) the article. ILYAZ:71.132.238.123 09:33, 2 June 2006 (UTC)

[edit] Roll axis

The 198.208.159.17 6th October edit here perpetuates a terminology problem, that my previous attempt had avoided. According to the SAE the roll axis joins the two roll centres. Fair enough. BUT the sprung body does not necessarily roll about the roll axis. It is a bad name. Now, on rereading my previous definition I'm not actually very happy with that either, it seems to me that first of all you have to define what you mean by a roll axis (in a 6dof system) and then you can perhaps describe where that axis is in the general sense.
