BMR Suspension TAS002 - Manual (Page 11)

52. The above image shows how the setup should look once adjusted correctly. The vehicle
should be set to the desired ride height. At this height, the rearend should be centered in
the body (side-to-side) with the Watts link vertical (straight up and down) and the Watts
link bars as level as possible. Once the above is verified, tighten all mounting bolts. All
½” mounting bolts should be tightened to 80 ft/lbs. It is also very important to tighten the
jam-nuts on the Watts link arms and Control arms.
53. 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.
54. 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. If you are out of spring adjustment on the shock and the suspension is
bottoming out, 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,
should angle upward slightly from rear to front (front mount higher than rear mount). If
they are level or angled oppositely, lower the rear mounting point. This angle helps
determine weight transfer upon acceleration. Each vehicle, depending on front-to-rear
weight distribution will vary slightly and favor a “sweet” spot but a slightly upward angle
of 1-2 degrees generally is optimal.
