Rut rolling, pipe clipping, or getting too low on the apron of a sweeper seems like it could happen with just about any amount of roll stiffness. These never seem as violent. Does this make sense?

I agree on the tire changing. As everyone knows, tires are everything in racing. I'm thinking that before I try anything too drastic with chassis setup, I should try just about every different tire combination I have in my tire box.
