now whats the diff in buildin a 4 link/ wishbone 3 link.... and buildin a set of lowers(paralla bars) and a panhard bar... pretty much the same set up as the front? i seen great flex outa the fronts???...
the more triangulation of the uppers and also the lowers, the less "rear steer" you get. The 4 link with track bar works better in the front due to the drag link and track bar being paralel to eachother, and as the front sus. cycles the drag link end stays the same distance from the pitman arm end. Not causing bump steer.
No matter what someone tells you a triangulated front will Never be as bump steer free as a stock front end. Theres people out there that swear that their 3-4k$ Teraflex LCG system doesnt have any pump steer. thats not poss with the geometry unless its a full hydro steer.
The rear doesnt need this type of geomerty to function in top form, so therefor a 3 or 4 link and trian. uppers with either trian. lowers or not, dont need the track bar allowing for a much more bind free setup as well as still lessor flex steer. The longer the lowers, if a triang upper only, the less steer you get under articulation.
All in all IMO a 4 link with track bar is the best front setup period, and a triang. upper and lower rear is the best, but a trian. upper only in the rear is still a very good setup.
More then anything though is doing alot of calc's to get the right numbers for your lift, weight, wheelbase, link angles and attachment locations.
