4. Setup and Installation
Professional installation is highly recommended. Improper installation can lead to vehicle damage, poor performance, or safety hazards. A few modifications might be required for some vehicles.
4.1 Pre-Installation Checks
- Verify all components are present and undamaged according to the package contents list.
- Ensure the vehicle is on a level surface and properly secured with jack stands.
- Gather all necessary tools, including wrenches, sockets, spring compressors (if needed for specific steps), and torque wrenches.
4.2 General Installation Steps (Consult a professional or vehicle-specific guide for detailed steps)
- Safely lift the vehicle and remove the wheels.
- Carefully remove the OEM suspension components (struts, springs, shock absorbers).
- Install the new MAXPEEDINGRODS coilover assemblies. Ensure proper orientation of the top mounts and secure all bolts to manufacturer specifications.
- Connect any stabilizer links or other associated components.
- Repeat for all four corners of the vehicle.
- Lower the vehicle and perform an initial alignment check. A professional alignment is crucial after installation.

5. Operating and Adjustments
Your MAXPEEDINGRODS coilovers offer multiple adjustment options to fine-tune your vehicle's handling and ride characteristics.
5.1 Ride Height Adjustment
The ride height can be adjusted by rotating the lower spring perch on the threaded shock body. Use the provided adjustment wrenches. Ensure the vehicle is safely supported before making adjustments.
- Loosen the locking collar.
- Rotate the lower spring perch to raise or lower the vehicle.
- Tighten the locking collar securely after adjustment.
- Always adjust both sides of an axle equally to maintain balance.

5.2 Pre-Load Spring Tension Adjustment
Pre-load refers to the initial compression of the spring. This adjustment affects the initial stiffness of the suspension and can be adjusted using the collars above the main spring.
- Loosen the locking collar.
- Rotate the spring perch to increase or decrease spring pre-load.
- Tighten the locking collar securely.
- Incorrect pre-load can affect ride quality and handling. Consult a suspension specialist if unsure.
5.3 Damper Force Adjustment (24 Ways)
The damper force (rebound and compression) can be adjusted in 24 levels to suit various driving conditions and preferences. The adjustment knob is typically located at the top of the strut for front coilovers and at the bottom for rear shocks.
- Full Soft (0 clicks): For a comfortable daily driving experience.
- Spirited Driving (approx. 16 clicks): Provides a balance of comfort and improved handling for enthusiastic driving.
- Full Stiff (24 clicks): Ideal for occasional track days or maximum performance, offering minimal body roll.
Turn the adjustment knob clockwise for stiffer damping and counter-clockwise for softer damping. Always adjust both sides of an axle equally.
5.4 Camber Adjustment
The front coilovers feature pillow ball top mounts which allow for camber adjustment. This adjustment should be performed by a professional alignment technician.
- Loosen the bolts on the top mount.
- Slide the top mount to adjust the camber angle.
- Tighten the bolts securely.
- A professional wheel alignment is essential after any camber adjustment.
6. Maintenance
Regular maintenance will ensure the longevity and optimal performance of your coilovers.
- Regular Cleaning: Keep the coilover bodies, springs, and adjustment collars clean from dirt, salt, and debris. Use mild soap and water.
- Inspect Rubber Boots: Periodically check the fitted rubber boots for tears or damage. These protect the damper from contaminants.
- Check for Leaks: Inspect the shock absorbers for any signs of oil leaks. A leaking shock absorber indicates a seal failure and requires replacement or repair.
- Torque Checks: Periodically check the torque of all mounting bolts, especially after the initial installation and after significant driving.
- Lubrication: Apply a thin layer of anti-seize lubricant to the threaded sections of the shock body and adjustment collars to prevent seizing and allow for easier future adjustments.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive Noise (clunking/rattling) | Loose mounting bolts, worn bushings, incorrect pre-load, damaged pillow ball mount. | Check and re-torque all bolts. Inspect bushings and pillow ball mounts for wear. Adjust spring pre-load. |
| Uneven Ride Height | Unequal ride height adjustment between sides. | Measure and adjust ride height evenly on both sides of the vehicle. |
| Poor Handling/Unstable Ride | Incorrect damper settings, improper alignment, incorrect spring rates, damaged components. | Adjust damper settings. Get a professional wheel alignment. Inspect for damaged components. |
| Stiff/Harsh Ride | Damper set too stiff, excessive spring pre-load. | Soften damper settings. Reduce spring pre-load (ensure minimum required pre-load is maintained). |
If you encounter persistent issues, it is recommended to consult with a qualified automotive technician.
8. User Tips
- Break-in Period: Allow for a break-in period of approximately 500 miles after installation. During this time, avoid aggressive driving and allow the suspension components to settle.
- Post-Installation Alignment: Always get a professional wheel alignment immediately after installing coilovers to ensure proper handling and tire wear.
- Gradual Adjustments: When adjusting damper force or ride height, make small, incremental changes and test the vehicle's behavior before making further adjustments.
- Seasonal Adjustments: Consider adjusting damper settings for different seasons or driving conditions (e.g., softer for winter, stiffer for track days).
