Introduction
The Eibach Pro-Spacer is designed to enhance vehicle aesthetics and handling by increasing track width. This product, when installed, positions the wheels further out, filling the wheel arches for a wider stance and improved stability. It is manufactured from high-tensile strength aluminum alloy, ensuring precise fitment and exceptional wheel balance.
This manual provides essential information for the correct installation, operation, and maintenance of your Eibach Pro-Spacer. Please read all instructions carefully before proceeding with installation or use.
Safety Information

- Ensure all components are clean and free from debris before installation.
- Use appropriate tools and torque specifications.
- Regularly inspect wheel spacers and lug nuts for tightness and wear.
- Do not exceed the recommended torque values.
- Ensure sufficient thread engagement for lug nuts after spacer installation.

Setup and Installation
This section outlines the general steps for installing Eibach Pro-Spacers. Specific vehicle requirements may vary. Always refer to your vehicle's service manual for wheel and lug nut torque specifications.
- Prepare the Vehicle: Park the vehicle on a level, stable surface. Engage the parking brake. Loosen the lug nuts on the wheel(s) to be fitted with spacers.
- Lift and Secure: Safely lift the vehicle using a jack and support it with jack stands. Remove the lug nuts and then the wheel.
- Clean Mounting Surfaces: Thoroughly clean the vehicle's hub mounting surface and the back of the wheel spacer. Ensure there is no rust, dirt, or debris that could prevent flush contact.
- Install Spacer: Place the Eibach Pro-Spacer onto the vehicle's hub. Ensure it sits flush against the hub.
- Secure Spacer (if applicable): If your spacer system requires it, use the provided hardware to secure the spacer to the vehicle's hub. Torque these bolts to the manufacturer's specifications.
- Mount Wheel: Place the wheel onto the installed spacer. Ensure the wheel sits flush against the spacer.
- Install Lug Nuts/Bolts: Install the new, longer lug nuts/bolts (if provided or required) or the original lug nuts/bolts (if using a hub-centric spacer that uses existing studs). Hand-tighten them.
- Lower Vehicle: Carefully lower the vehicle until the wheel just touches the ground, but the full weight is not yet on the wheel.
- Torque Lug Nuts/Bolts: Using a torque wrench, tighten the lug nuts/bolts in a star pattern to the vehicle manufacturer's specified torque. Do not overtighten.
- Final Lowering: Fully lower the vehicle and remove the jack and jack stands.
- Repeat: Repeat the process for all wheels where spacers are to be installed.

Operation and Driving Considerations
Once installed, Eibach Pro-Spacers are designed to integrate seamlessly with your vehicle's wheel system. While they improve handling and appearance, it's important to be aware of the following:
- Initial Check: After driving the first 50-100 kilometers (30-60 miles), re-check the torque of all lug nuts/bolts. This is crucial as components can settle.
- Handling Changes: Widening the track width can alter the vehicle's handling characteristics. Drive cautiously until you are accustomed to the changes.
- Clearance: Ensure there is adequate clearance between the tire/wheel and fender, suspension components, and brake lines, especially during full steering lock and suspension compression.
- Legal Compliance: Verify that the use of wheel spacers complies with local traffic laws and regulations.
Maintenance
Regular inspection and maintenance are vital for the safe and reliable operation of your Eibach Pro-Spacers.
- Periodic Torque Check: Re-check the torque of the lug nuts/bolts at regular service intervals (e.g., every 5,000-10,000 km or 3,000-6,000 miles) or whenever wheels are removed and reinstalled.
- Visual Inspection: Periodically inspect the spacers for any signs of damage, cracks, corrosion, or deformation. If any damage is observed, replace the spacer immediately.
- Cleaning: Keep the spacers and mounting surfaces clean to prevent corrosion and ensure proper fitment.
Troubleshooting
If you encounter issues after installing your Eibach Pro-Spacers, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Wheel vibration/wobble | Improper installation, loose lug nuts, unbalanced wheels, incorrect hub-centric fitment. | Re-check lug nut torque. Ensure spacer is flush against the hub. Verify correct hub-centric rings (if applicable). Have wheels balanced. |
| Tire rubbing | Spacer is too thick, incorrect wheel offset, suspension issues. | Verify proper clearance before driving. Consider a thinner spacer or different wheel/tire combination. Consult a professional. |
| Lug nuts loosening | Insufficient torque, improper thread engagement, damaged threads. | Re-torque lug nuts after initial driving. Ensure full thread engagement. Inspect threads for damage. Replace damaged components. |
If troubleshooting steps do not resolve the issue, discontinue use and consult a qualified automotive technician.
