On four links, a drag-only set-up, they work great once set-up but wow, too many stories on fellas who really had a hard time adjusting the bars to get the set-up they needed or wanted. A true trailered race car suspension. That and a broken Heim joint (they always seem to break at the first thread after the Y shape of the bearing end) or cracked weld on the tubes will put you in a world of hurt!
Never saw or even heard of any Cal-Trac suspension break or bend on some mighty fast cars. That and the set-up is as pretty straight forward and, as mentioned, once it's right, leave it forever. Not so true with four links as 'messing' with a pretty good set-up gets fellas, looking for a tad better hook, way off track afterwards unless they keep a measurement log book.
Heck, even some old slapper bar cars (think: Lakewood) run darned fast too!
