fbi does suck and their kit sucks too, I could fabricate a better kit in the dark with one hand tied behind my back.
check out my build tubbin n dubbin in suspension I used the same FBI kit
ya gotta set it up based on the wheel size yer goin with also desired lift and ride height must be decided first. what about spindles ? I am using drop spindles. with the lower ball joint mounted on top.
Point is , a lot of figurin has to be done first.
As for your front locator arm , I cut mine off, I would suggest triangulating the lower control arm if you do.
Twisted minis posted a pic of that some time ago.
Tyler, Flameds10 chromed his, and he is rollin 20's too.
You must have to loosen them to get that much travel.
I will help you if i can
first thing is what wheel size, get your wheels with rubber, and that is where its best to start , to avoid any
re-dos
