Understanding Ohlins Road & Track Coilovers
Ohlins is renowned for its high-performance suspension systems, and the Road & Track coilovers are designed specifically for street and track use. They offer adjustable ride height and damping, allowing for a customizable driving experience. Here are some key features:
- Adjustable Damping: Fine-tune your suspension for different driving conditions.

Tools and Materials Needed
Before you begin the installation process, gather the following tools and materials:
- Socket set
- Torque wrench
- Spring compressor
- Jack and jack stands
- Ohlins Road & Track coilovers
- Owner’s manual
Step-by-Step Installation Process
1. Prepare Your Vehicle
Start by parking your M3 on a flat surface and engaging the parking brake. Loosen the lug nuts on the wheels without removing them entirely. Then, lift the vehicle using a jack and secure it with jack stands.
2. Remove the Stock Suspension
To remove the stock suspension, follow these steps:
- Remove the front wheels.
- Disconnect the sway bar end links.
- Unbolt the strut assembly from the top and bottom.
- Carefully remove the strut assembly from the vehicle.
3. Install Ohlins Coilovers
With the stock suspension removed, it’s time to install the Ohlins coilovers:
- Use a spring compressor to compress the spring on the Ohlins coilover.
- Insert the coilover into the strut mount location.
- Secure the coilover with the provided hardware.
- Reconnect the sway bar end links.
4. Adjust Ride Height
Before lowering the vehicle, adjust the ride height of the coilovers. This can be done by turning the threaded collar on the coilover. Aim for a height that balances aesthetics and performance. Lowering the car too much can lead to issues with suspension travel and alignment.
5. Reinstall Wheels and Lower the Vehicle
Once the coilovers are installed and adjusted, reinstall the wheels. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.
6. Perform a Wheel Alignment
After installation, it is essential to get a professional wheel alignment. This ensures that your M3 handles correctly and maximizes tire life.
Setting Up Ohlins Damping
After installing the coilovers, setting up the damping is crucial for optimal performance. Ohlins coilovers come with adjustable damping settings that can be tuned for comfort or performance. Here’s how to adjust the damping:
- Locate the damping adjustment knobs on the coilovers.
- Turn the knobs to adjust the compression and rebound settings.
- Start with the manufacturer’s recommended settings and adjust based on your driving style.
Testing and Fine-Tuning
Once everything is installed and adjusted, it’s time to take your M3 for a test drive. Pay attention to how the car handles and make notes of any adjustments needed. Fine-tuning the suspension can take time, but it’s worth the effort to achieve the perfect setup for your track days.
Conclusion
Installing and setting up Ohlins Road & Track coilovers on your BMW M3 can significantly enhance its performance on the track. By following these steps, you can ensure a successful installation and setup process. Remember to take your time with adjustments and enjoy the improved handling and responsiveness of your M3.
