How to install SPC Performance 72125 – Camber Arms for Infiniti G35 and Nissan 350z
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 shifting to correct cars that have bottomed out, or for vehicles used in skids. These new arms allow for precise shifting when fine-tuning the suspension alignment angles needed when racing or drifting. The hub and caliper shims extend toward the center of the wheel, allowing the forged and fabricated arm to make up to a 5-degree and +/- 1-degree camber change in total. pitcher change. Through the use of a sliding and rotating 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, 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: 1.8h/side
Required: 1 kit per axle
APPLICATIONS
Infiniti: 2003 – 07 G35 Coupe. 2003-05 sedan
Nissan: 2002 and 2008 350Z
Before beginning, record alignment readings, determine amount of pitch and/or pitch change needed. The control arm installation should only provide a +.5 degree to -1.5 degree camber change along with the set forward 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 vehicle with body pressure welds and support 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 spindle. Support the spindle.
4. Remove bushing bolts securing upper control arm to body. Remove the upper control arm.
5. Using a small puller, remove the ball joint stud seat from the original ball joint.
6. Install new adjustable control arm to vehicle and lightly tighten bushing support bolts. Match the new arm to 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 press it back into the hitch hex.
8. Reinstall the adjustable ball joint assembly on the control arm. Install the washer and nut and tighten lightly.
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 ft-lbs. (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 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 4 bolts holding bearing hub and remove hub from axle along with brake guard. Be careful not to damage the rear of the bearing hub that supplies the ABS signal.
4. Install the hub spacer so that 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 supplied 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 bolts to 58-72 ft-lb (78-98 Nm).
6. Using the stock ABS bracket bolt, install the ABS sensor to the upper hub retaining bolt using the two shims provided and the retaining bracket as shown in Fig. #2. Tighten the bolt making sure the ABS sensor does not touch the swivel 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 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 pitch change needed and check the caster reading. Raise the vehicle enough to gain access to the camber adjustment nut.
11. To adjust the 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 ft-lbs. (162Nm).
Always check for proper clearance between suspension components and other vehicle components.
12. Recheck alignment readings, adjust toe and road test vehicle. Confirm that the anti-lock brake and traction control systems are working properly.
13. If the hub shim set has been installed and the ABS or traction control light is on, the air gap will need to be adjusted as follows:
has. 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) of clearance and the tip of the sensor should be square to the hub. If both shims are removed, make sure the tip of the ABS sensor does not touch the rotating hub.
