How To Adjust Bc Coilover Height

If you're looking to improve your vehicle's handling, aesthetics, or ride height, adjusting your BC coilover height is a vital step. Properly setting your coilovers not only enhances the look of your car but also ensures optimal performance and safety. Whether you're lowering your vehicle for a sleek stance or raising it to improve ride comfort or clearance, understanding the correct procedure is essential. In this guide, we'll walk you through the comprehensive steps on how to adjust BC coilover height effectively and safely.

Understanding BC Coilover Components

Before diving into the adjustment process, it’s important to familiarize yourself with the key components of BC coilovers that influence height adjustment:

• Threaded Shock Body: The part of the coilover where the spring seat and height adjustment collar are threaded onto.
• Spring Seat / Collar: The adjustable ring that compresses or releases the spring, allowing for height adjustments.
• Locking Collar: Usually a second ring, used to lock the position of the spring seat after adjustment.
• Strut / Damper: The main shock absorber that connects to the vehicle’s suspension.

Understanding these components helps you perform adjustments correctly and avoid damaging your coilovers.

Tools Needed for Adjustment

To adjust your BC coilover height safely and effectively, gather the following tools:

• Socket wrench set (typically 14mm or 17mm sockets depending on your coilover model)
• Adjustable spanner or coilover adjustment wrench
• Wire brush or cleaning cloth (to clean threads)
• Jack and jack stands (to lift and secure your vehicle)
• Wheel chocks (for safety)

Preparation Before Adjustment

Proper preparation ensures safety and precision during the adjustment process:

• Park on a level surface: Ensure your vehicle is on a flat, stable surface.
• Loosen the parking brake: To prevent movement during adjustments.
• Lift the vehicle: Use a jack to lift the car and secure it with jack stands. Remove the wheels for easier access.
• Ensure the suspension is unloaded: Do not perform adjustments with the vehicle under load to avoid inaccurate settings.

Step-by-Step Guide to Adjust BC Coilover Height

Follow these detailed steps to adjust your BC coilover height properly:

1. Remove the Wheel and Access the Coilovers

After securing the vehicle on jack stands and removing the wheels, locate the coilovers. They are typically mounted between the suspension arm and the strut tower.

2. Clean the Threads

Use a wire brush or a clean cloth to remove dirt, debris, and corrosion from the threaded portion of the coilover. This ensures smooth adjustment and prevents damage to the threads.

3. Loosen the Locking Collar

Using an adjustable spanner or coilover wrench, loosen the locking collar (if present). Turn it counter-clockwise to free the spring seat from its locked position. Do not remove it completely; just loosen enough to allow movement of the spring seat.

4. Adjust the Spring Seat / Collar

To lower the vehicle:

• Turn the spring seat clockwise to compress the spring and lower the ride height.

To raise the vehicle:

• Turn the spring seat counter-clockwise to decompress the spring and increase ride height.

Make small adjustments—typically 1-2 turns at a time. Remember, turning the collar clockwise lowers the ride height, and turning it counter-clockwise raises it.

5. Ensure Symmetry and Measure

Adjust both sides of each axle equally to maintain proper alignment and handling. Use a measuring tape or ride height measurement tool to verify the height from a fixed point (such as the wheel arch or fender) to the ground for consistency.

6. Lock the Adjustment

Once the desired height is achieved, retighten the locking collar against the spring seat to secure the setting. Use the wrench to tighten it firmly, but avoid over-tightening which could damage the threads or components.

7. Reassemble and Lower the Vehicle

Replace the wheels, tighten the lug nuts to manufacturer torque specifications, and carefully lower the vehicle back onto the ground. Remove the jack stands and ensure the vehicle is stable.

8. Final Check and Test Drive

After adjusting the height, perform a test drive to assess ride quality and handling. Make any necessary fine-tuning adjustments after the initial test drive if the height or handling isn't as desired.

Important Tips for Safe and Effective Adjustment

• Adjust in small increments: Large turns can cause uneven adjustments or damage.
• Maintain equal height on both sides: For proper handling and aesthetics.
• Check clearance: Ensure sufficient space between tires and suspension components to prevent rubbing.
• Recheck torque: After a short drive, re-tighten the lock collars to account for settling.
• Consult the manual: Always refer to your specific BC coilover model’s manual for detailed instructions and torque specifications.

Additional Tips for Maintaining Your Coilovers

Proper maintenance extends the life of your coilovers and preserves ride quality:

• Regular cleaning: Clean the threaded areas to prevent dirt buildup that can hinder adjustments.
• Lubrication: Use appropriate lubricant on threads if recommended by the manufacturer.
• Periodic inspections: Check for leaks, corrosion, or damage periodically.
• Professional alignment: After significant height adjustments, have a professional wheel alignment performed to ensure optimal handling and tire wear.

Conclusion

Adjusting the height of your BC coilovers is a straightforward process but requires attention to detail and safety precautions. Properly setting your coilover height can dramatically improve your vehicle's appearance, handling, and comfort. Always take your time, make incremental changes, and verify measurements to achieve the best results. If you're unsure or uncomfortable performing these adjustments yourself, seek assistance from a professional mechanic or suspension specialist. With the right approach, you can enjoy a customized ride that looks great and performs optimally for your driving needs.
