How to install SPC Performance 72125 – Camber Arms for Infiniti G35 and Nissan 350z

SPC Performance’s arm / chock kit is the first on the market to provide a substantial amount of positive camber change. It has more than enough tilt and caster changes to correct for cars that have been lowered, or for used vehicles in skids. These new arms allow for precise shifting by precisely adjusting the suspension alignment angles needed when racing or skidding. The caliper hub and shims extend into 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 rotating ball joint, technicians can adjust both the camber and the caster to save tires and improve handling and tire contact with the surface. The kit includes everything you need, including the ABS sensor bracket, shims, and arms for both sides of the vehicle. Fits G35 and 350Z applications.

Adjustment range

Camber: -1.5 degrees to +3.5 degrees Caster ± 1.0 degrees
Installation time: 1.8 h / side
Required: 1 kit per axle

Infiniti: 2003-07 G35 Coupe. 2003-05 sedan
Nissan: 2002 and 2008 350Z

Before you begin, record the alignment readings, determine the amount of pitch change and / or pitch required. The control arm installation should only provide +.5 degrees to -1.5 degrees of tilt shift in conjunction with the indicated caster shift.

If more change in camber is needed, install the bushing shim set 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 by the body pinch welds and support it with jack stands. Remove the front tire and wheel assembly.

3. Remove the cotter pin and nut from the upper ball joint and remove the ball joint from the shaft. Support the shaft.

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 to the vehicle and lightly tighten the hub support bolts. Match the new arm to the old arm to make sure the correct arm is installed on each side.

7. If wheel adjustment is necessary, 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 hooking hexagon and rotate it as illustrated in figure n. 1 for the required wheel change, 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 tighten slightly.

9. Install the original ball joint upper seat onto the ball joint bolt, then install the bolt on the shaft. Install the supplied flat washer then the supplied ball joint castle nut and tighten to 40-46 lb-ft. (54-63 Nm) Install a new cotter pin.

NOTE: Be sure to install a flat washer under the castle nut to prevent the control arm from separating from the shaft.

10. Load the suspension to normal ride height and tighten the upper control arm bushing bolts to 48-55 ft-lb (65-75 Nm).

11. If shim set is not required, follow steps 10-12 below.

Hub Shim Installation Kit

1. Remove the brake caliper and support it out of the way of the brake line and 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 hub from the shaft along with the brake guard. Be careful not to damage the back of the bearing hub that supplies the ABS signal.

4. Install the hub spacer so that the thickest part of the wedge is facing up and the 4 bolt holes are aligned 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 two lower holes. Tighten the bolts to 58-72 ft-lb (78-98 Nm).

6. Using the original ABS bracket bolt, install the ABS sensor to the upper hub retaining bolt using the two supplied shims and the retaining bracket as illustrated in Fig # 2. Tighten the bolt ensuring that it the ABS sensor does not touch the slewing bearing hub. Fig. 3

7. Reinstall the brake rotor.

8. Install the caliper spacer between the caliper bracket and the caliper with the thickest side up. Tighten the caliper bolts to 112 ft-lb (150 Nm). Make sure the brake rotor turns 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 required and check the wheel reading. Raise the vehicle high enough to access the camber adjustment nut.

11. To adjust the camber, loosen the adjusting nut and move the adjustable ball joint in or out of the control arm slot to obtain the desired camber reading, then tighten the adjusting nut to 120 lb-ft. (162 Nm).

Always check that there is adequate clearance between suspension components and other vehicle components.

12. Recheck the alignment readings, adjust toe-in, and test the vehicle on the road. Confirm that the antilock brake and traction control systems are working properly.

13. If the hub shim set is installed and the ABS or traction control light is illuminated, the air gap should be adjusted as follows:

For. Remove the bolt and retaining bracket from the ABS sensor. Remove a shim and reinstall the bracket, sensor, and bolt. If the problem persists, the second shim can be removed.

B. The ABS sensor gap can be checked if necessary. Using a non-magnetic feeler gauge, check the gap between the sensor and the back of the bearing hub. There should be no more than. 016 “(.41 mm) clearance and the sensor tip must be square with the hub. If both shims are removed, make sure the ABS sensor tip does not touch the rotating hub.
