I spent many days cycling the suspension up and down (real time not cad
) then moving one of the mounting points at a time to get it to do what I wanted it to do, I also made sure to keep the 2 lower links running inboard as wide apart as possible to reduce the stress on the links and heims. It works very well with minimal plunge, I would design your own then you know it works, there are plans out there that have never been tested except for on cad and we all know that does not mean it will work in the real world.
Also even if you did get a design that works but needed to move one of the mounts a small amount to clear the gearbox or A caliper mount etc that could easily throw it all out and cause big problems.
