I much prefer the urethene bushed ends on the street. The heim joints are a bit much for the street, hard to keep clean and lubed and just plain noisy and rattly. IMO best left for the drag cars.

Ladder bars work fine on the street, just subject to binding up a bit more then a 4 link. I've ran them on the street, just have to remember what you have on the rear when you start playing on a curvy road! They will tend to build a bit of push into the front end if you get back on the power a bit soon...
