No, I havn't used a 4 link calculator. So If I move my lower links up at the axle end it'll help? I Got this idea of mounting on a comp rock rig I saw on TV it acts like a rock slider. with rear flex steer as bad as it is right now, it's no good. As long as It's have a little, no big deal thanks for all the info
it will help reduce longitudinal displacment of the link end throughout the useable arc of the suspension travel. As stated before, however, unless you triangulate, you won't be ablt to fully eliminate the flex steer.
