Interesting. I thought that a stiffer bar decreases roll but gives you less grip on that end? For example when FWD guys put on a stiff rear bar, they have less roll but less grip at the rear to give them more oversteer. Or do I have that mixed up
Herb Adams of Pontiac GTO and Trans Am fame in the 60s swore by stiffer sway bars and soft springs. He also added rigidity throughout the chassis to help control body roll.
He wrote a very good book where he explains in laymans terms his engineering philosophy.
