Not sure the link works but if it does,it's worth watching.Not a real indepth show by any stretch,but Ian does give a fairly decent over view of how a 4 link rear suspension works.He touches on rear steer slightly which is a major contributor to why the 4the Gens have a tendenancy to wobble after they've been lowered.
