4. Setup and Installation
This section outlines the general steps for installing the maXpeedingrods Coilovers. Specific vehicle service manuals should be consulted for detailed removal and installation procedures of the original suspension components.
4.1 Pre-Installation Checks
- Ensure the vehicle is on a level surface and securely supported.
- Inspect all coilover components for any shipping damage.
- Familiarize yourself with the components, including the adjustable camber plates and dust boots.

4.2 General Installation Steps (Professional Installation Recommended)
- Safely lift the vehicle and remove the wheels.
- Remove the original suspension components (struts, springs, shocks).
- Install the new maXpeedingrods coilover units. Ensure all bolts are torqued to manufacturer specifications.
- For front coilovers, align the top hat bolts with the vehicle's strut tower.
- For rear shocks and springs, ensure proper seating of the springs and secure attachment of the shocks.
- Reinstall wheels and lower the vehicle.
- Perform an alignment after installation to ensure correct vehicle geometry.
5. Operating and Adjustment
Your maXpeedingrods Coilovers offer adjustable damping and ride height to fine-tune your vehicle's performance and stance.
5.1 Damping Adjustment (24 Levels)
The coilovers feature 24 levels of damping rebound force adjustment. This allows you to customize the ride comfort and handling characteristics.
- Full Soft: For a comfortable driving experience.
- 16 Clicks from Full Stiff: Recommended for spirited driving.
- Full Stiff: Suitable for occasional track use.
Adjust damping by turning the knob located at the top of the coilover (or bottom for some rear applications). Turn clockwise for stiffer damping, counter-clockwise for softer damping. Always adjust both sides of an axle equally.

5.2 Ride Height Adjustment
The coilovers allow for independent ride height adjustment, typically within a 1-3 inch lowering range from stock. This adjustment is performed using the threaded body and locking rings.

Procedure for Height Adjustment:

- Loosen the lower mount (A) and locking ring (B) using the provided C spanners.
- Increase or decrease the thread distance to change the ride height. Turning the lower mount up will lower the vehicle; turning it down will raise it.
- Once the desired height is achieved, tighten the lower mount (A) and locking ring (B) securely against each other to prevent movement.
Note: Always adjust both sides of an axle to the same height to maintain vehicle balance. After any height adjustment, a wheel alignment is recommended.
6. Maintenance
Regular inspection and maintenance will prolong the life and performance of your coilovers.
- Regular Inspection: Periodically check all mounting bolts for tightness. Inspect the shock bodies, springs, and dust boots for any signs of damage, leaks, or corrosion.
- Cleaning: Keep the coilovers clean from dirt, salt, and debris, especially the threaded sections, to ensure smooth height adjustment. The anodized shock body and powder-coated lower mount offer anti-corrosion protection, but regular cleaning is still beneficial.
- Dust Boots: The full-length dust boots protect the piston shafts. Ensure they are intact and free from tears.
7. Troubleshooting
If you experience issues with your coilovers, consider the following common troubleshooting steps:
- Unusual Noises (Clunking/Squeaking):
- Check all mounting bolts for proper torque.
- Inspect for any loose components or contact between the coilover and other vehicle parts.
- Ensure springs are properly seated.
- Uneven Ride Height:
- Verify that both coilovers on an axle are adjusted to the same height.
- Check for any bent or damaged components.
- Poor Handling/Ride Quality:
- Re-evaluate damping settings. Adjust to a softer or stiffer setting as desired.
- Ensure tire pressures are correct.
- Confirm that a proper wheel alignment has been performed after installation or height adjustments.
If problems persist, consult a qualified automotive technician or contact maXpeedingrods customer support.
