not to scale drawn relative to placement and chassis geometry.
Width between center of rear tires equal to width between front tires
In our case the distance is 75 inches
Thank you Jaxworks Allen Cox and Russ Mathis for teaching us how to do this
Rear pivots line up to point at either the differential or a central part on the transaxle (also known as the THIRD member)
Transaxle on a rail/buggy is moved toward the front for weight and to allow the axle to swing in an arc matching the Camber of the rear arms (about 5 degrees)
A straight line off the steering arm of the
spindle points to the same point on the trans that the rear pivots point at.
Steering arm length is determined by how much response you require in your steering wheel--shorter arms turn fasterFront spindle to rear axle length should be the same on both sides and camber set equal before adjusting toe in/out, set rear toe first
Bump steer can be eliminated or at least minimized by making sure all the arms and tie rods are parallel and the inner heim joins line up
Control arm attachment points line up with rack mounting points
and intersect on the center line of the chassis
Upper and Lower Control
arms are parallel in all axis.. the EYE does not LIE
Vertical (looking down)
Horizontal (looking back)
Tie rods match angle of control arms(parallel)
Shocks are to be placed 1/3 the distance between the front and rear upper control arm mounting points
if a shock leans in at 45 degrees... the wheel moves
2 inches for every 1 inch of shock movement.
18 inches of travel is possible with a 10 inch shock
Vertical distance between control arm mounting points is determined by the spindle height (heim to heim)
