Outer Limits 4x4 Board

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

Hey

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 .

hope this helps

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!!

Working out your actual COG is close to impossible for the average DIYer but if you're super keen, read here: http://www.jeepaholics.com/tech/cog/

However, the generally accepted dodgy way is to measure from the top bolt on your car's bellhousing. Fair bit easier.

Pretty much everything you wanted to know about the 4-link calculator from the guy who designed it.
