Bad pints, super high roll center will cause jacking in corners.  Lack of camber gain will not exploit camber thrust and will have tires tilt in the wrong direction under roll.

Good points, lack of lateral displacement will have good straight line stability.  Lots of travel and no bumpsteer.

Should be good for hitting big bumps in a straight line.

The high roll center is close to the CG so there is a lot of geometric anti roll, hence little body roll. The high roll center is not a good thing though due to the jacking effect.

so is his application (suzuki sidekick or other offroad types) where they have a large range of travel, jacking wouldn't be such a big deal vs a race car with limited droop. is that correct?

I think for low speed dirt it migth be pretty good. High speed like off road racing, probably not.

Good luck getting all of that underneath a passenger car and having room for a driver and a piece of paper as cargo.
