SPC Performance’s Arm/Shim Kit is the first on the market to provide a substantial amount of positive camber change. It has more than enough camber and caster to correct cars that have been lowered, or for vehicles used in drifts. These new arms allow for precise shifting when fine-tuning the suspension alignment angles required when racing or drifting. The caliper hub and shims extend toward the center of the wheel, allowing the forged and fabricated arm to make a full camber change of up to 5 degrees and +/- 1 degree. pitcher change. Using a sliding and swiveling ball joint, technicians can fine-tune both camber and caster to save tires and improve handling and tire-to-surface contact. The kit includes everything you need, including the ABS sensor bracket, chocks, and arms for both sides of the vehicle. Fits G35 and 350Z applications.

Before you begin, record the alignment readings, determine the amount of camber and/or camber change needed. The control arm installation should only provide a camber change of +.5 degrees to -1.5 degrees along with the indicated trail change.
If more camber change is needed, install the hub shim kit which will provide an additional 2 degrees of positive camber.
Control Arm Installation
1. Always check for loose or worn parts, tire pressure, and tire wear.
2. Raise the vehicle with the body pressure welds and support it with jack stands. Remove the front tire and wheel assembly.
3. Remove the upper ball joint key and nut and remove the ball joint from the spindle. Support the spindle.
4. Remove the bushing bolts holding the upper control arm to the body. Remove the upper control arm.
5. Using a small puller, remove the ball joint stud seat from the original ball joint.
6. Install the new adjustable control arm on the vehicle and lightly tighten the bushing bracket bolts. Match up the new arm with the old arm to ensure the correct arm is installed on each side.
7. If the wheels need to be adjusted, loosen and remove the washer from the large adjusting nut on the upper ball joint, then remove the ball joint assembly from the control arm. Separate the locking plate from the hitch hex and rotate it as illustrated in Fig. #1 for the required wheel change and then push it back into the hitch hex.
8. Reinstall the adjustable ball joint assembly on the control arm. Install the washer and nut and lightly tighten.
9. Install the original ball joint upper seat on the ball joint stud, and then install the stud on the spindle. Install the supplied flat washer and then the supplied ball joint castle nut and torque to 40-46 lb-ft. (54-63 Nm) Install a new key.
NOTE: Be sure to install a flat washer under the castle nut to prevent the control arm from separating from the spindle.
10. Load the suspension to normal ride height and torque the upper control arm bushing bolts to 48-55 lb-ft (65-75 Nm).
11. If the shim kit is not required, follow steps 10-12 below.
Hub Shim Installation Kit
1. Remove the brake caliper and hold it out of the way so there is no stress on the brake line, then remove the brake rotor.
2. Remove the ABS sensor at the rear of the hub.
3. Remove the 4 bolts holding the bearing hub and remove the axle hub along with the brake guard. Be careful not to damage the rear of the bearing hub that supplies the ABS signal.
4. Install the hub spacer so the thickest part of the shim is facing up and the 4 bolt holes line up correctly.
5. Install the plastic dust shield so that the ABS sensor opening points directly into the upper hub retaining bolt hole. Now install the bearing hub and brake shield. Use the two longer bolts provided on the top two hub bolts. The bolt with the 8mm threaded hole installs into the top of the hub directly above the opening in the plastic dust shield. Use the original bolts in the bottom two holes. Torque the bolts to 58-72 ft-lbs (78-98 Nm).
6. Using the stock ABS bracket bolt, install the ABS sensor to the upper hub retainer bolt using the two shims provided and the retainer bracket as illustrated in Fig. #2. Tighten the bolt making sure the ABS sensor does not touch the pivot bearing hub. Fig.3
7. Reinstall the brake rotor.
8. Install the caliper spacer between the caliper bracket and the caliper with the thickest part facing up. Torque the caliper bolts to 112 foot-pounds (150 Nm). Make sure the brake rotor spins freely.
9. Reinstall the tire and wheel assembly. Remove the vehicle from the jack stands and lower the car.
10. Determine the amount of camber change needed and check the caster reading. Raise the vehicle high enough to gain access to the camber adjustment nut.
11. To adjust camber, loosen the adjusting nut and move the adjustable ball joint in or out in the control arm slot to obtain the desired camber reading, then tighten the adjusting nut to 120 lb-ft. (162Nm).
Always check for proper clearance between suspension components and other vehicle components.
12. Recheck alignment readings, adjust toe-in and road test vehicle. Confirm that the anti-lock braking and traction control systems are working properly.
13. If the hub shim kit has been installed and the ABS or traction control light is illuminated, the gap will need to be adjusted as follows:
A. Remove the ABS sensor retaining bolt and bracket. Remove one shim and reinstall bracket, sensor, and bolt. If the problem persists, the second wedge can be removed.
b. The ABS sensor gap can be checked if necessary. Using a non-magnetic sensor gauge, check the gap between the sensor and the back of the bearing hub. There should be no more than 0.016″ (0.41mm) gap and the sensor tip should be square to the hub. If both shims are removed, make sure the ABS sensor tip does not touch the rotating hub.
