1. Introduction
This manual provides detailed instructions for the installation, operation, maintenance, and troubleshooting of your Godspeed MAXX Coilover Lowering Kit (MMX2118). Designed for the BMW 7-Series E65 (2002-2008), this kit offers enhanced vehicle dynamics and adjustable ride height and damping. Please read this manual thoroughly before attempting any installation or adjustment to ensure proper function and safety.
2. Safety Information
Improper installation or adjustment of suspension components can lead to serious injury or vehicle damage. Always prioritize safety.
- Professional Installation Recommended: It is highly recommended that this product be installed by a qualified automotive technician.
- Vehicle Support: Always use appropriate jack stands or a vehicle lift to securely support the vehicle when working underneath it. Never rely solely on a jack.
- Personal Protective Equipment: Wear safety glasses, gloves, and other appropriate personal protective equipment during installation.
- Torque Specifications: Always refer to your vehicle's service manual for correct torque specifications for all fasteners.
- Electronic Dampers: For BMW 7-Series E65 models equipped with electronic dampers, installing this kit will result in a service light illuminating on the dashboard. This is expected as the electronic damper system will no longer detect the factory components.

4. Installation Guide
This section outlines the general steps for installing the Godspeed MAXX Coilover Kit. Specific procedures may vary slightly depending on your vehicle's exact configuration. Always consult your vehicle's service manual for detailed removal and installation steps for OEM components.
General Installation Steps:
- Prepare Vehicle: Park the vehicle on a level surface. Engage the parking brake. Loosen the lug nuts on the wheels.
- Lift and Secure: Safely lift the vehicle using a hydraulic jack and secure it with jack stands at appropriate lift points. Ensure the vehicle is stable before proceeding.
- Remove Wheels: Remove the lug nuts and then remove the wheels from the vehicle.
- Remove OEM Suspension: Carefully disconnect and remove the original shock absorbers and springs. This typically involves disconnecting brake lines, ABS sensors, sway bar links, and upper/lower mounting bolts. Exercise caution to avoid damaging these components.
- Install New Coilovers: Install the Godspeed MAXX Coilovers. Ensure the upper mounts are correctly oriented. Secure all mounting bolts, but do not fully tighten them until the vehicle is at ride height.
- Initial Adjustments: Perform initial ride height and damping adjustments as desired (refer to Section 5).
- Reassemble: Reconnect all disconnected components (brake lines, ABS sensors, sway bar links). Ensure all lines and wires are routed correctly and not pinched.
- Install Wheels: Reinstall the wheels and hand-tighten the lug nuts.
- Lower Vehicle: Carefully lower the vehicle to the ground.
- Final Torque: With the vehicle at ride height, fully tighten all suspension mounting bolts to the manufacturer's specified torque. Tighten lug nuts to specification.
- Alignment: After installation, it is crucial to have a professional wheel alignment performed to ensure proper handling and tire wear.
5. Operation and Adjustment
The Godspeed MAXX Coilovers offer independent adjustment for both damping force and ride height, allowing you to fine-tune your vehicle's suspension characteristics.
5.1 Damping Force Adjustment
Your coilovers feature 40 precise levels of damping force adjustment, allowing you to switch between a softer, more comfortable ride and a stiffer, track-oriented setup. The adjustment knob is typically located at the top of the shock shaft (for front coilovers) or at the bottom of the shock body (for rear coilovers, depending on design).
- To Adjust: Turn the adjustment knob clockwise for stiffer damping (harder ride) and counter-clockwise for softer damping (more comfortable ride).
- Counting Clicks: Start from the fully stiff position (fully clockwise) and count the clicks as you turn counter-clockwise to achieve your desired setting. Ensure all four coilovers are set to the same damping level for balanced handling.
5.2 Ride Height Adjustment
The ride height is adjusted using the lower bracket, which allows for full-length adjustment without compromising shock travel. This ensures comfort is maintained even at lowered settings.
- To Adjust: Use the provided adjustment wrenches to loosen the locking collars on the lower bracket.
- Raise/Lower: Rotate the lower bracket to raise or lower the vehicle's ride height. Turning it clockwise will lower the vehicle, and counter-clockwise will raise it.
- Secure: Once the desired ride height is achieved, tighten the locking collars securely to prevent movement.
- Evenness: Ensure that the ride height is adjusted evenly on both sides of the vehicle (front and rear) to maintain proper balance and handling.
6. Maintenance
Regular maintenance will prolong the life and performance of your Godspeed MAXX Coilovers.
- Regular Inspection: Periodically inspect the coilovers for any signs of damage, leaks, or loose components. Check dust boots for tears.
- Cleaning: Keep the coilovers clean, especially the threaded sections and adjustment collars, to prevent corrosion and ensure smooth adjustments. Use mild soap and water.
- Lubrication: Apply a thin layer of anti-seize lubricant to the threaded sections and adjustment collars annually to prevent seizing.
- Torque Check: Re-check all mounting bolts and nuts for proper torque after the first 500 miles of driving and periodically thereafter.
- Replacement Parts: Shock absorbers can be replaced when worn out. Replacement cartridges are available, allowing for cost-effective maintenance without needing to purchase a complete new coilover system.
7. Troubleshooting
This section addresses common issues you might encounter with your coilover system.
| Problem | Possible Cause | Solution |
|---|---|---|
| Unusual Noises (clunking, squeaking) | Loose mounting bolts, worn bushings, damaged components, spring bind. | Check all mounting bolts for proper torque. Inspect bushings and other components for wear or damage. Ensure springs are seated correctly. |
| Uneven Ride Height | Incorrect ride height adjustment, uneven spring preload. | Re-measure and adjust ride height on all four corners. Ensure spring preload is consistent if applicable. |
| Poor Handling / Instability | Incorrect damping settings, improper alignment, loose components. | Adjust damping settings (ensure all four are consistent). Have a professional wheel alignment performed. Check all suspension components for tightness. |
| Leaking Shock Absorber | Damaged seal, internal component failure. | Contact Godspeed support for replacement or rebuild options. |
