37. Using Image 21 on the previous page as a guide, thread one of the two Watts link bars
onto the Watts link pivot and mount the other end into the drivers side mount. The bar
should be installed into whichever mounting hole places the Watts link bar at the most
level position while the suspension is loaded. Insert one of the provided ½” x 3.25” bolts.
Thread a stainless washer and nut over the exposed thread and tighten to 80 ft/lbs.
NOTE: the Watts link pivot should be vertical (straight up and down) with the suspension
loaded. It will be necessary to adjust the rod end in
order to achieve this.
38. Duplicate the previous step for the passenger
side Watts link bar.
39. As shown in Image 22, use a plumb bob to
determine proper axle location. NOTE: it is
not necessary to remove the wheels and tires
to accomplish this, the measurement can also
be taken from the wheel itself. Hold the
plumb bob against each wheel well in the
same position and measure the axle location in
relation to the fender. Adjust the rod ends
until each side is equal while the Watts link
pivot remains vertical (not angled). Once all
adjustments have been made, tighten all mounting bolts and then tighten the rod end jam-
nuts on the Watts link bars.
40. Except for final setup, the installation is complete. Double-check all mounting bolts for
tightness and inject a few pumps of grease into all of the grease fittings using the supplied
silicone based lube. Re-grease the fittings initially after a few miles and then every other
oil change thereafter.
41. Re-install the fuel tank and plumb the fuel lines.
SETTING UP YOUR NEW TORQUE ARM SUSPENSION
1. Ride Height. The very first thing that should be done is to establish the desired ride
height. Previously the height was determined when the Watts link was setup during the
installation process. Most of the time, this setting will be fine however driving the car
will settle the suspension slightly and best determine if the height will need to be altered.
Drive the car 10-20 miles to insure a consistent ride height and verify suspension travel.
NOTE: the suspension should not bottom out except in extreme road irregularities or
very heavy dips. It is important to make sure the shocks do not bottom out to insure long
shaft seal life. If you are out of spring adjustment and the suspension is still bottoming
out, try changing the lower shock mounting locations and re-adjusting the springs. This
will give more shock travel and increase the spring tension. In some circumstances with
heavier vehicles, it may be necessary to increase the spring rate. In this case, please
contact BMR for technical help in selecting proper rates.
2. Trailing Arm Angles. With the final vehicle height determined, check the trailing arm
angles. For proper anti-squat, the trailing arms, when viewed from the side of the car,
