Ok I just got done with my 4 link rear on my ZJ and now I'm about to start the 3 link in the front...I ended up running about 65-80% anti squat in the rear. Question is should I be looking for around the same numbers for the front 3 link or should I go alittle higher in the AS numbers? Right now I've got a pretty solid setup in the calculator that I can actually fit under my rig and make work. The AS number is 86%, with a roll axis angle of 3 and roll center hieght at about 30". Just wanted to know what you guys would think.
Thanks

iirc, its not really AS in the front, it would be anti-dive because of the configuration of the suspension..... therefore when you hit hte brakes your AS #s in the calc are gonna be how much the front of the vehicle noses towards the ground... with high antidive numbers your typical nose dive wont occur as much... id say most passenger cars have a rather low antidive number...
 
lower number... Roll axis doesn't matter quite as much on a steer axle.

Try to get the roll center close to the rear height, and it'll drive predictably at higher speeds.

Just some rules of thumb..

Higher AD numbers also tend to want to extend the suspension before climbing obstacles..(think short-arm TJ)
