Note:  For participants in the Factory Five Challenge several of these components should be welded in place.  (This also applies to street cars used on the track with race compound tires.)  Specifically, these components include:  the panhard bar mount on the frame, the upper control arm mount on the frame, and the upper control arm mount on the axle.  Care should be taken when welding to the axle housing to ensure that no warping of the axle tubes occurs.
Important:  If you have the battery mounted in the standard street car location, it will need to be moved to the trunk.  It will not clear the panhard bar mount.
Installation Instructions
1.  Put the car on jack stands with the stands under the frame in the rear.  Make sure that the car is well supported before doing any work underneath it.
2.  Put your jack under the axle to take tension off of the limiting straps.
3.  Remove the quad shocks and brackets from the frame and rear axle.  They will not be used.
4.  Unbolt the shocks and limiting straps from the rear axle allowing them to hang from the top mount.
5.  If you do not have coil-overs, remove the springs by lowering the axle.  CAUTION:  Removing springs can be VERY dangerous.  Run a safety chain through the spring and to the frame and use extreme caution.
6.  One at a time unbolt each rear lower control arm and replace the traction lock bracket with the competition version.  The shock will bolt back in using the same spacer in front and the 1/8" shim toward the rear.  The lower control arms should be mounted in the upper set of holes as an initial setting.

7.  The frame mount for the panhard bar can be mounted next.  The mount attaches to the inside of the quadshock brackets and has a front leg that attaches to the rear of the left main frame rail.
8.  Bolt the mount in place replacing the smaller quad shock bolts with 1/2" bolts, but do not tighten fully.  The hole for the front leg mount needs to be drilled in the back of the rail.  You can either mark it with a marker or start the hole with a drill through the sleeve on the mount.  Make sure before drilling that the hole is lined up close to the center of the 2"x3" vertical tube so that a nut can be attached on the back of the bolt from the bottom.
9.  Once the hole has been drilled, install the panhard mount and tighten all the bolts.
10. Install a jam nut on each of the rod ends, remembering that two of them are left hand thread.
11. Thread each rod end into the panhard bar and upper arm until approximately 1/4" of thread is showing between the jam nut and end of the rod end.
12. Mount the panhard bar to the car using the 5/8" bolts and spacers.  It will be necessary to adjust the length some to fit, make sure that you adjust the same amount on both sides.  There should never be less than 3/4" of threads screwed into either the panhard bar or the upper arm.
13. Once the panhard bar is in place, you can remove the upper control arm on the passenger side.
14. With the arm removed, you can attach the bracket to the axle for the new upper arm mount.  The bracket clamps around the axle, with the lower leg attaching to the hole where the counter weight was attached.  If you still have this weight on your axle, you will have to remove it.
15. Before clamping the mount tight, check the clearance around the axle vent tube.  If the mount interferes with this tube, then you need to grind or file some material away.  Once this is done, tighten the bolt on the lower leg first, then tighten the four bolts on the axle clamp.
16. The frame mount for the upper arm mounts to the horizontal 2"x3" steel tube behind the seats, next to the old upper control arm mount.  If you will not be using the four link again, this mount can be cut off or partially cut off to create more space.
17. Position the mount on the 2x3 toward the passenger side next to the old upper control arm mount.  (You also must make sure that there is room for the nut to mount the upper control arm).  The mount runs parallel to the frame with the hole offset toward the rear and should be lined up with the axle mount such that the upper control arm runs parallel to the frame.  If the weld for the old bracket interferes with the new one, you can remove some material from the rear corner of the new one to get it to sit flat on the frame.
Upper mount (trunk floor not installed)
18. Once positioned, mark and drill the holes for the bracket.  It will be easier to start with a small drill and work your way up to the 5/8" bit.
19. Bolt the bracket in place using the backing plate on the top side (inside the trunk) and the two long 5/8" bolts.  It will probably be necessary to get someone to hold the top of the bolt while you tighten the nut.
20. Install the rod ends with jam nuts in the upper control arm and bolt the arm in place using the spacers.
21. You can now remove the drivers side upper control arm.
22. To set the alignment, make sure that your ride height is where you want it, then adjust the pinion angle.  We usually run about 2 degrees up on the rear axle, but you can adjust this to fit your particular set-up.
23. The panhard bar can also be set left to right, as well as leveled.
24. Double check all your nuts and bolts, and make sure that all four jam nuts are tight.
