Hello!! Im currently doing a 4 link conversion in the rear of my 1991 suzuki sierra. I've got all of the control arms, coils, coil mounts etc figuired out, but i just started playing with the 4link calculator - and buggered if i can get my head around it!! It appears that i need the following measurements for the calculator to work: Front and the rear un-sprung mass, the vehicle mass, the COG etc. But, the cab needs to be on for me to be able to get most of these measurements.. but i have already got my cab off!! I also cant figuire out all of this X Y Z stuff either Can anyone please give me some advise?? Thanks heaps

I have just been playing with this stuff on my 40, will see how well i can help you out .
From what i can work out on the pirate calculator =-
x = length of control arm forward from centre line of rear axle to link end
y = 1/2 of horizontal separation of link ends at frame
z = height of link ends from ground
If you already have you coils and rates worked out then i guess your helfway there .
uh huh... that does help a bit yeah.. thanks mate!! Just gotta work out the COG now.. then "hopefully" it will all start working!! argh... bloody confusing!!
