MAR Series, Bind Free, Adjustable GR40 Anti Roll Bar
1) Assemble the bar as shown in Picture A. Hold entire assembly in place under car. Locate the ARB mounting nut plate locations on bottom of subframe. End links should be held vertical. The nut plate should be centered front to rear directly under the oval hole in the side of the subframe. See Picture B. Clean off Bottom of subframe in this area for welding.

2) Be sure ARB is positioned centered and square to car. Arms must be free of interference with subframe. Weld nut plates to chassis.
3) If you prefer to use the softer settings of the bar, a second nut plate mounted adjacent and forward will allow use of the softer settings. Most V-8 applications require the 3 stiffer settings.
4) Install end links so that they are vertical when chassis is at ride height. We recommend the center hole to start. Be sure to neutralize bar loading with driver weight in car during chassis setup. Note: Spacers may be cut or shimmed as required to affect this as it will depend on variables such as the control arm length. Also, varying the spacer length will make small changes in the stiffness of the ARB by altering the motion ratio. The further outboard the end link ball is mounted on the arm and the more vertical the link, the more effective the ARB.
