Anti - squat

Hey guys, I searched and searched for this but was unable to find anything on this site, maybe someone can direct me.
What anti - squat % is a good target? Or where is the lengthly discussion about anti - squat for 4 - linked trucks?
I was going to shoot for 80% because it seems like that would be good number for my area. We have about 900 acres of sand dunes here so there won't be sustained high speed, mostly point and shoot stuff and the rest will be playing on trails. Any input is appreciated.

Here's a quoted explanation:
"With anti-squat geometry the suspension is extending in reaction to the torque applied to it, forcing the wheels down onto the ground.
With negative anti-squat, the suspension is compressing in reaction to the torque applied to it, trying to lift the rear wheels off the ground and up into the body, so the back bumper is dropping towards the road, not because of weight transfer, but because the rear wheels are being sucked up into the body."
My experience:
I usually built the upper links with multiple holes to experiment with weight transfer characteristics depending on desired traction. Pm me and I can email you a 4 link geometry calculator the summarizes some of the numbers in a modle and gives you force numbers and percentages. It may help you out.

Thanks a bunch, the suspension design links page has a ton of great stuff!
I am assuming you put the multiple holes in the brackets on the top of the rear end?

I put multiple holes on the upper frame side.

Oh ya and don't exceed 60 inches in length on links as a rule, it makes a very slowly responding rear suspension whitch translates to bucking if you do. I realize its a bronco and 60 inches isn't really possible but its a guideline none the less.
