Triangulated systems that work need to consider several things. Wheelbase, roll center, Center of Gravity, loaded and unloaded weight.
Effective systems can be designed to force the weight down or to neutral load at the launch, or anti squat.
A poorly designed system will raise the frame up and try to drive under itself...
I've been looking at all the kits out there and I just don't see them working the way they should. They'll probably work ok, but not great... I'll look at their instruction and see what is needed for setup.
The 4 links work fantastic, but take up a stupid amount of room and their a nightmare to adjust. It took me 2 months to design one for my rock crawler. different sport, but the principal is the same. Keep traction on the ground with a low roll center. Still needed a sway bar, however I was running 32" coilovers.
The 3 link with panhard is much easier to build, much more forgiving if your mount is off by a degree or two.
Here are few programs to punch numbers into and see what it'll take.
