The installation of coilovers on your Lexus IS can significantly enhance both handling and ride quality. This modification is popular among car enthusiasts who seek improved performance and a more aggressive stance. In this article, we will discuss the benefits of coilovers, the installation process, and essential tips for achieving the best results.
Benefits of Coilovers
Coilovers are a type of suspension system that combines coil springs and shock absorbers into a single unit. They offer several advantages over traditional spring and shock setups:
- Improved Handling: Coilovers allow for adjustable ride height and damping, which can significantly enhance cornering performance.
- Customizable Ride Quality: Different settings enable drivers to tailor the suspension to their preferences, whether for daily driving or track use.
- Aggressive Stance: Lowering the vehicle improves aesthetics and can lower the center of gravity, further enhancing handling.
- Increased Stability: A well-tuned coilover system can improve overall vehicle stability during high-speed maneuvers.
Preparing for Installation
Before beginning the installation process, it is crucial to gather the necessary tools and materials. Here’s what you will need:
- Coilover kit specific to the Lexus IS
- Jack and jack stands
- Socket set and wrenches
- Torque wrench
- Pry bar
- Spring compressors (if necessary)
- Safety glasses and gloves
Ensure that you work in a well-ventilated area and take safety precautions. It’s advisable to have a friend assist you during the installation for added safety and efficiency.
Step-by-Step Installation Process
1. Raise the Vehicle
Using a jack, lift the front or rear of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
2. Remove the Wheels
Take off the wheels to access the suspension components. Use a socket set to remove the lug nuts and store them in a safe place.
3. Remove the Stock Suspension
Begin by disconnecting any components connected to the stock strut, such as brake lines and sway bar links. Then, remove the bolts securing the strut to the knuckle and the top mount inside the engine bay.
4. Install the Coilovers
Position the new coilover in place of the old strut. Secure it to the knuckle and top mount, ensuring all bolts are tightened to the manufacturer’s specifications. Use a torque wrench for accuracy.
5. Adjust Ride Height
Before reinstalling the wheels, adjust the ride height to your desired level. Follow the manufacturer’s instructions for the proper method of adjustment.
6. Reinstall the Wheels
Once the coilovers are securely installed, put the wheels back on and tighten the lug nuts in a crisscross pattern to ensure even pressure.
7. Lower the Vehicle
Carefully lower the vehicle back to the ground using the jack. Once on the ground, double-check all connections and bolts to ensure everything is secure.
Post-Installation Checks
After installation, it’s essential to conduct a few checks to ensure everything is functioning properly:
- Inspect for any leaks around the coilovers.
- Check all bolts and connections for tightness.
- Make sure the ride height is level on all corners.
- Test drive the vehicle to assess handling and comfort.
Conclusion
Installing coilovers on your Lexus IS can dramatically improve handling and ride quality. With proper preparation and attention to detail during the installation process, you can enjoy a more responsive and enjoyable driving experience. Always remember to follow up with regular maintenance and adjustments to keep your suspension system performing at its best.
