- Spring compressors
- Torque wrench
- Suspension grease
- Safety glasses
- Work gloves
Preparation
Before starting the installation, ensure that you have a clean workspace and all necessary tools and materials at hand. Safety is paramount, so wear safety glasses and gloves throughout the process.
1. Lift the Vehicle
Using a jack, lift the front of the Subaru BRZ and secure it with jack stands. Repeat this process for the rear of the vehicle. Ensure the vehicle is stable before proceeding.
2. Remove the Wheels
Using a socket set, remove the lug nuts from each wheel and take off the wheels. This will provide access to the suspension components.
Front Coilover Installation
3. Remove the Stock Struts
Locate the top strut mounts under the hood. Remove the nuts securing the strut mounts using a socket set. Then, remove the bolts connecting the strut to the lower control arm and the steering knuckle.
4. Install KW Coilovers
Using spring compressors, compress the stock springs and remove them from the struts. Install the KW coilover assembly by securing it to the lower control arm and steering knuckle. Tighten the bolts to the manufacturer’s specifications.
5. Secure the Top Mounts
Reinstall the top strut mounts and secure them with the nuts. Ensure everything is tightened properly. Apply suspension grease to the bushings and joints for optimal performance.
Rear Coilover Installation
6. Remove the Rear Struts
For the rear struts, remove the lower bolts connecting the strut to the control arm and the upper mounting bolts from inside the trunk. Carefully remove the stock struts.
7. Install KW Rear Coilovers
Install the KW rear coilovers in the same manner as the front. Ensure the lower bolts are secured to the control arm and the upper mounts are tightened properly.
8. Adjust Ride Height
Before securing everything, adjust the ride height of the coilovers according to your preference. Refer to the KW manual for recommended settings.
Final Steps
Once both the front and rear coilovers are installed, recheck all bolts and connections to ensure they are tightened to the specified torque settings. Replace the wheels and lower the vehicle back to the ground.
9. Test Drive
After installation, take the Subaru BRZ for a test drive. Check for any unusual noises or handling issues. Adjust the coilovers as needed based on your driving preferences and track conditions.
Conclusion
Installing KW coilovers on your Subaru BRZ can significantly enhance its track performance. By following this step-by-step guide, you can ensure a successful installation that will improve your driving experience. Always remember to perform regular maintenance and adjustments to keep your suspension in optimal condition.
