Cary, I'll look around for some of the info on them that I'm talking about. All the places that make or sell them seem to say that they are good, but most guys that have used them or build rear set-ups don't recommend them. Coil-overs and ladder bars are a better way to go. I would also say that for a car that is going to see much street time that you shouldn't go with ladder bars. There is not enough twisting movement allowed in the rear-end. They are made for straight line use. For a street car you need to have a good amount of up and down and twisting movement to the rear-end.
