Someone mentioned Ron Roads so I figured I'd post a picture of the bottom of his car I believe this device is used for controlling rotation Maybe but I'm not a hundred percent sure
In this pic that is a wishbone, its used to control housing left to right movement, basically keep it centered in the chassis. He also has a anti-roll bar to control body roll. And Smith bars instead of caltracks. Not real sure why the wishbone with leafs but it certainly would not hurt.
