Ladder Bars will work on most any rear drive car. They are easier to understand how to get them to work and many people end up getting them to work without even understanding the concept of how they work and why to adjust what.
A 4-link and a 3-link is superrior if adjusted and tuned right. Most 4 link cars would be better off with Ladder Bars.
With Ladder Bars there is not that much avalable to adjust.
Even with Ladder Bars, I do prefer them to have adjustable links for pinion angle changes and pre-load adjustability.
In my opinion, I have the best, the strongest, and most adjustable Ladder Bars there is.
