USE OF THIS PRODUCT IS ACCEPTANCE OF SELLER’S DISCLAIMER OF WARRANTY!
By their very nature, competition components are constantly pushed to their limits. While our components

damage, or injury – direct or indirect – arising from the use of or inability to determine the use of any

INSTRUCTIONS
1. Begin by jacking up the rear of the car, place jack stands under rear end housing.
2. Loosen and remove the bolts securing the stock panhard bar.
3. Remove the stock panhard bar.
4. Install the Spohn panhard bar onto the car using the OEM bolts and make the nuts hand
tight only at this time. The long part of the bar with the adjuster goes on the upper driver's
side mount and the short part of the bar mounts to the rear end (See Illustration 1 below).
5. Lower the car to the ground. Measure the distance from the edge of your rim to the outside
of the fender well. You should have the same distance on both sides of the vehicle.
6. If your rear is not centered you can now adjust your panhard bar. One end of the Panhard
Bar adjuster is left hand threaded and the other end is right hand threaded. To adjust the
length of your Panhard Bar simply put a wrench on the hex in the center of the adjuster and
turn the adjuster clockwise or counter-clockwise to lengthen or shorten the Panhard Bar. This
will move your rear to the left or to the right, depending on which way you turn the adjuster.
7. When you have your rear centered, tighten the jam nuts, and then tighten the mounting
bolts to 60 ft/lbs.
8. The poly bushings come pre-lubed. DO NOT use petroleum-based grease on your poly
bushings! Poly bushings must be lubricated with synthetic silicone based waterproof grease.
These are the manufacturer’s recommendations to prevent pre-mature bushing wear, and will
keep things "squeak-free". You can order this grease from Spohn Performance using our Part
#902. Do not over grease the bushings! You only need a couple pumps of grease. Over
greasing will cause the bushings to balloon from the hydraulic pressure inside of the sleeve
and they will fail.
9. Jam nuts are known to work loose over time. To prevent this we recommend that after you
have the panhard bar set to your desired length you apply some REMOVABLE strength (blue)
Loctite to the adjuster threads and then tighten up the jam nuts on each end of the adjuster.
Note: To check your rear for center drop a plumb bob off of the edge of your quarter panel
and measure from the plumb string to the face of your rim edge. You want the same distance
on both sides of the car.
