My 2 cents on this one. I use them, I love them, there not a big cost and it makes a great deal of difference in the handling of the car. But as with any thing it needs to be installed right to optimize its ability. This is also something that is best done with all the weight in and on the car and supported by the tires. Try and mount the frame rail bracket so that the link bar is as close to level as possible. Weld it to the frame if at all possible there is a lot of load on this at times.
