Unequal length 4 bars are entirely different on their geometry and how the settings can be changed to react to track conditions. The shorter bar is always on the top but the mount holes are drilled in the mount plates on an arc that follows the angle of the bars so you can change bar holes on either the front or rear mounts and change what the chassis is doing..... Sound confusing? Well, unequal length four bars are somewhat confusing until you spend some time studying their geometry and how bar mount positions change what the chassis is doing.... The Doorslammers Chassis Book is probably one of the most complete and thorough books on the science of bar adjustments.

Can't really see where the unequal length 4 bar setup would do much on the street unless you just want the "eye candy" effect.... Even at the track I have seen many both new and experienced drag racers dial their traction and hook up right out of the car by making the wrong adjustments!!!!!

IMO for street or dual purpose machines, either the parallel or triangulated four bar is the way to go. The unequal length 4 bars would be best left for the race only cars... They will work on the street and can be set up with polyurethene bushings, just a lot of hassle for the little bit of advantage they would ever give if the bars were occasionally adjusted to match the ever changing conditions on the street!!!!
