need help understanding minute center

While the total process is good to know you have to visualize the changes as the car reacts! It never stops moving unless the car does! Start by using a plumb bob to mark across the front lower ball joints on the floor! Measure point a to b and 1/2 mark center! Do the same on the rear axle after finding a suitable spot on the axles ends! Mark the rear line and find center! move the car and square off of front center line to the rear line. A chalk line and help is needed as well as a square and a good tape! Measure ft. corners to rear cross to insure square my math! Check the off set and wedge of rear by the front As most rears should be 2 inches to the right and open or closed 3/8 depending on angles and roll. Off sets of rims can get you closer if off set too much after adjustments are maid! This only tells you where it is and not where it needs to be! If your frame is leaned left one inch in the front with one inch of roll out, correct springs and wheel off sets, air psi set and driver in the car, Camber can be set! Lean of the tires! 3to4+ rt. side and -1to-2 on the lt. Set the toe out 1/2 inch! Upper A arms should allow you to move the upper ball joints behind the lowers! 6-12 degrees works for us! While if designed for other set ups or moved mounts in this respect can be very tricky! adjustable links is the way to go when legal or re-design the mounts! Tie rods need to level out under full roll!
