impala2door70,
Tell us what you have in all details, how much horsepower you are planning and how much weight and how quick are you trying to go.
I do prefer a good long tube 4-link above everything else if I am doing all the tuning, but with many of my customers, ladder bars, and other suspension set-ups are the best way to go. You would be surprised at what can be done even to an old trailing arm car or truck for example.
Are you running in a class that has suspension limitations or requirements?
