So, I've starting looking into the 3 link setup for the front, been reading a **** load of stuff on Pirate 4x4.. think my head is going to explode!
Found a nice thread about front setups.

This post is very useful to explain the anti squat calculation on the rear

Also been messing with the Excel spread sheet
Has anyone built a 3 link setup before??
Bit of very useful info on the configuration outcome!
With non-parallel links that converge "at the same crossmember," the IC is always right there at the crossmember and cannot move in relation to the COG. The only thing that changes as the suspension cycles is the slope of the line from the axle to the IC, and therefore where that line intersects.
With parallel links, the IC is an infinite distance away in front of the vehicle, and changes height depending on the slope of the links. IOW, the IC location changes position as the suspension cycles, as well as the slope of the line.
With non-parallel links that don't converge at the same crossmember, the IC location and slope changes position as the suspension cycles, just like the parallel links, but not as much depending on how close to parallel or actually converging they are.
