The vehicle should be on a level surface before you start.
1. Before any removal begins, disconnect the battery. But you knew that.
2. Remove upper control arms, coil springs and shocks. To give you more
working room you may want to remove the spindle as well.
3. Passenger side pictured. Front >>> Remove the existing Upper Shock
mount. Cut along the dotted line and the facotry weld (arrow).
DO NOT CUT OFF THE UPPER CONTROL ARM MOUNT!

4. After the shock mount is removed, you will need to remove the inner spring
cup and clearance the hole to about 4 ½” in diameter. This is best done with a
plasma cutter or oxyacetyline torch.
5. Test fit the Chicane upper shock bracket into place, centered over the hole.
Notice one side of the bracket has a notch in the base. This side goes towards
the front of the vehicle. Mark the width of the bracket on the control arm mount.
Using these marks as a guide, cut out a notch so that the shock bracket butts up
flush against the outer side of control arm mount.

6. This is what you should end up with. Do not proceed to welding at this time.

7. Assemble the coilover shocks as per the supplied instructions. Be sure to place the
“T” bar in the lower mount and secure it with external snap rings. Make sure the snap
rings are seated in the grooves correctly.

8. Do not skip this step. Mock up the lower control arm and coilover shock
assembly to make sure the upper Chicane mount is located in the correct
location. This also ensures that all shock components clear the frame. To allow
you to work with both hands and keep everything in place, support the lower
control arm and shock assembly. We recommend a small piece of chain or nylon
rope. Align them so that the lower control arm is level to the ground and set the
shock approximately in the middle of its travel. This will be close to the finished
ride height. You must be sure the shock is not mounted in a way that binds the
bushings and/or bearings.
9. Assemble the Chicane Bracket to the shock top eyelet. Align barcket into
position so that the shock is centered in the hole and will travel without hitting the
frame. Some slight trimming of the bracket notch you previously made may be
necessary. When you are sure everything is aligned properly, TACK weld the
upper Chicane mount in this location.

10. On some frames, depending on shock and spring combination, it may be
necessary to clearance the inner section of the control arm mount as seen in the
photo below. Do not do this with the shock installed.
11. Remove the shock assembly and then remove the spring from the shock.
Reinstall the shock into the lower control arm and the Chicane bracket to test
again for any binding throughout the control arm's range of motion. Now that you
have double checked everything and there is no bind and no clearance issues,
you can final weld the Chicane upper bracket in place.
12. Once all welding is completed you can paint and/or reassemble all
suspension components.

Be sure to double check all the fasteners! Set the car to the approximate

before aligning the car.
Note: Do not drive the car until an alignment has been performed by a
COMPETANT alignment or race car shop.
