This assumes, of course, that the roll center was below the center of
gravity before raising it. What it is actually saying is that a
shorter roll couple reduces roll angle. It's inaccurate and misleading
to simply say that higher roll centers result in lower roll angles.
That said, just like I clarified to Justin, roll angle isn't what
causes cars to roll over. It's high roll rates and a sudden impact
against the bump stop (IMHO) that does it. There's nothing wrong
with lots of body roll provided it doesn't adversely affect alignment
or aerodynamics... Until you hit the bump stops.
