4 link figures (1 Viewer)

[hobiesbestfriend]

Have been playing around with the excel spreadsheet for designing a 4 link and have been fine with most of it, except when it comes to actually using those numbers that the calculations spit out for you. Wondering what figures I should be aiming for as far as better or worse. Anit-Squat: higher or lower wanted or is it as close to 100%
I understand how to adjust my input figures to make things change, I just don't really know what change is good and what is detrimental. Anyone got a good summary explanation? I realize some of it is determined by weight etc.. what is the best way to determine what your truck is going to weigh once all is said and done?

And TRD put it so well

"Keep that AS down, over 100 requires a center limit strap. which equals the gayness"

remember that AS is only one of the many variables...

my AS is in the mid 80's....works excellent. I run a center limit, but only to control travel...it's only tight on decents or at full flex.

roll center IIRC you want as high as possible....

I haven't played with the latest calculator...but I understand it allows you to flex thru your suspension...keeping values consistent thru the range is important too...

also, "steering" of the axle as it flexes...my uppers are triangulated, my lowers splayed, and all 4 are 39" eye to eye....my rear steer is negligible...longer arms and not running them parallel both help to keep that controlled.

I am building my F&R over the winter, and will incorporate 3 holes in the frame side upper mount to allow for easy changes.. 1" works out to ~20-25% change in AS on my rig, but the middle hole is around 75%.

We now are working on a long arm kit for the fj40, and fj 80 avaliable for resale soon. Life time warranty on the control arms.
we'll keep you posted.
