Stentorian, now that I've got my head linked up with my brain, do you have a front strut brace?
Reason why I ask, is that with a heavier rear swaybar, helping to lead toward oversteer, that a front strut brace would tend to keep it toward neutral. If you added a rear strut brace without one in the front, wouldn't you tend to really push toward oversteer?
Just thinking, doesn't necessarily mean I'm right.
