How to Install and Adjust Aftermarket Coilovers
Upgrading to aftermarket coilovers is a popular modification among car enthusiasts seeking improved handling, a lower stance, and customizable suspension settings. This guide will walk you through the process of installing and adjusting aftermarket coilovers, ensuring a smooth and successful upgrade.
What You'll Need
Before you begin, ensure you have the following tools and materials:
- A set of aftermarket coilovers
- Jack and jack stands
- Socket set
- Wrench set
- Spring compressors (if applicable)
- Torque wrench
- Wheel chocks
- Lubricant (WD-40 or similar)
- Gloves and safety glasses
Pre-Installation Steps
- Safety First: Park your vehicle on a flat, stable surface, engage the parking brake, and place wheel chocks behind the wheels.
- Access: Use the jack to lift the vehicle and securely place it on jack stands. Never work under a vehicle supported only by a jack.
- Wheel Removal: Remove the wheels to access the suspension components.
Installation Process
Front Coilovers
- Remove Existing Suspension: Use your socket and wrench set to remove the bolts connecting the top of the strut to the vehicle. Then, proceed to remove the bolts at the bottom. Carefully take out the OEM strut assembly.
- Prepare Coilover: If your coilovers come with adjustable camber plates, set them to the desired initial setting.
- Install Coilover: Position the new coilover into place. Start by securing the top mount inside the engine bay, then attach the bottom of the coilover to the suspension components. Use a torque wrench to tighten all bolts to the manufacturer's specifications.
- Repeat: Perform the same steps on the other front wheel.
Rear Coilovers
- Access Rear Suspension: The process may vary depending on your vehicle. Generally, you'll need to remove interior panels or access covers in the trunk to reach the top mount bolts.
- Remove and Replace: Similar to the front, remove the existing suspension components and replace them with the new coilovers, ensuring all bolts are torqued to specification.
Adjusting Your Coilovers
Height Adjustment
- Measure: Before adjusting, measure the current height from the center of the wheel to the fender lip.
- Adjust: Most coilovers have a threaded body allowing for height adjustment. Turn the adjustment collar to raise or lower the vehicle to your desired height. Ensure both sides are even.
- Settle and Re-measure: After adjusting, roll the vehicle back and forth to settle the suspension. Re-measure and adjust as necessary to achieve your desired stance.
Damping Adjustment
If your coilovers have damping adjustment, you can fine-tune the ride quality and handling:
- Locate Adjustment Knobs: These are usually on the top of the coilover or on an external reservoir.
- Adjust: Turn the knob clockwise for stiffer damping and counterclockwise for softer damping. Start with the manufacturer's recommended settings and adjust based on your preferences.
Post-Installation
- Reinstall Wheels: Put the wheels back on and lower the vehicle to the ground.
- Alignment: It's crucial to get a professional wheel alignment after installing new suspension components to ensure proper handling and tire wear.
- Test Drive: Carefully test drive your vehicle to ensure everything is working correctly. Pay attention to any unusual noises or handling characteristics.
Conclusion
Installing and adjusting aftermarket coilovers can transform your vehicle's performance and appearance. While it requires some mechanical knowledge and patience, following these steps will ensure a successful upgrade. Always refer to the coilover manufacturer's instructions for specific details and torque specifications. Happy modding!
