3. Remove the Lower Control Arm bolt using an 18mm socket or wrench.

4. Slide passenger side bracket into place and align the holes, then reattach the axle damper. Do not fully tighten bolt. If your vehicle did not come with the weights installed, use the 2 supplied 30mm bolts.

7. Position arm in the lower hole and insert the Silver 100mm 10.9 bolt with the nyloc nut on the outside facing the wheel. Positioning may require use of pry bar. Tighten bolt to 129 ft/lb.

8. Switch to the driver’s side; if the car came equipped with weights, use a 15mm wrench and remove the weight, then use an 18mm wrench and remove the lower control arm bolt and move the control arm out of the way. (Figures 5 and 6)



9. Use an 18mm wrench to remove the panhard bolt so you can insert the bracket.

10. Inset Whiteline bracket over the stock bracket. Install the remaining supplied Yellow 100mm 8.8 bolt, gold center tube and nyloc nut as shown. Do not tighten yet.
