I hope we are not all getting worked up for nothing. All suspension and geometry are always compromises. Y'all are saying what's better or worse... but for what? The dynamics of launching a 600 HP car off the line at the drag strip are different than the side, braking, and accelerating loads required of a road racer and different again than the requirements of an oval racer. Even the surface requres different suspension.

Look at the Dodges at the dragstips of the 60's with the rear wheels moved forward and weight moved behind the rear axle. They certainly aren't concerned about polar moments of inertia; they are only concerned about weight transfer during the launch. I've looked at pictures of the JBL chassis and I can tell you as an ex road racer, that thing looks trick.

I was wondering though whether the rear control arms are parallel unequal arms or non-parallel unequal arms. If they are parallel, they have the same weaknesses as the Jags and Factory Five IRS's - the camber will actually go positive on sag. Richard, if you're still lurking around, maybe you could answer.

Can't we all just get along?
