4- Link Setup

try to make your links parallel when veiwed from the side (** Caution:  Gives axle considerable roll oversteer)

make them as long as you reasonably can

make them as flat as you reasonably can

make the roll axis (4-link) or roll center (3-link) as high as you reasonably can as this will lessen body roll on off-camber situations

A more horizontal roll axis will prevent roll induced rear steer effects.  Making the roll axis angle downward from rear to front will help lessen this effect making the vehicle easier to drive on the road.

high roll axis (or center) will make bump induced compression push the frame and body sideways in order to compress, which takes a lot of force to do quickly.

vertical separation should be 6" or more. More especially for more horsepower and/or bigger tires.

make the triangulated portion 40 degrees or more for decent lateral control

Lower the anti-squat, the less the hopping on climbs

Keep roll center as high as possible

Upper links should be roughtly 70% of lower link lengths; this ensures that as the axle moves away from the frame the anti-squat lessens allowing for less hop

Make verticle separation at frame mounts 75% of the verticle separation at the axle

Instant center is the intersection of the upper and lower links drawn from the side of the vehicle.  If parallel links, the instant center is infinite.  The higher the instant center, the more anti-squat, the lower the more squat.

draw a line from the contact patch of the rear tire up to the COG level directly above the front axle.  If the instant center is above this line, you have anti-squat, if below, you have squat

for double triangulated 4-link setups, the roll axis is the line drawn through the front and rear LCPs (link convergence points) from the side.

For single-triangulated 4-links, the roll axis goes from the rear LCP and runs parallel to the lower links.

100% anti-squat gives a neutral setting where forces are equal and opposite one another.  More AS and the rig will rise upon acceleration, less and it will squat.

Ideal setting is anti-squat between 50-80%

Negative or zero roll axis slope reduces/eliminates oversteer

3-Link Setup

Seems like anti-dive would be a good thing all around with a front 3-link.  Rises upon braking and drops upon acceleration up steep climbs.

Panhard seems to want to pull the axle toward the frame mount as it extends.  Is this a problem?  How is it overcome for the most part?

Caster should be set to 4 degrees

tow in should be 1/4" at the tread measured on flat tire

look at Ruffstuff's lower shock mounts

Frame height at 22-25" would be ideal

Look over pricing of All Pro stuff

draw a line from your front tire contact patch through the instant center. Take the height of where that line crosses the rear axle and divide by the COG height. Then multiply by the % of front braking and that is your % anti-dive.

Keep top link as close to center of axle and frame as possible

make lik as perpendicular to axle as possible

slight downward slop to the axle from the frame

keep 4-6" of vertical separation between uppers and lowers
