The Lexus IS is known for its sleek design and luxurious features, but for those looking to enhance its performance, adjustable coilovers and sway bars are essential modifications. This article will guide you through the installation process of these components, helping you achieve improved handling and ride quality.
Understanding Adjustable Coilovers
Adjustable coilovers are a popular upgrade for enthusiasts who want to fine-tune their vehicle’s suspension settings. They allow you to adjust the ride height and stiffness, which can significantly impact handling performance.
Benefits of Adjustable Coilovers
- Improved Handling: Lowering the center of gravity enhances cornering stability.
- Customizable Ride Height: Tailor the vehicle’s look and performance to your preference.
- Enhanced Comfort: Adjust stiffness to find the perfect balance between comfort and performance.
Tools and Materials Needed
Before starting the installation, gather the necessary tools and materials:
- Adjustable coilovers kit
- Sway bars kit
- Jack and jack stands
- Wrench set
- Sockets and ratchet
- Torque wrench
- Spring compressors
- Penetrating oil
- Safety goggles and gloves
Installing Adjustable Coilovers
The installation of adjustable coilovers involves several key steps. Follow this guide to ensure a successful installation.
Step 1: Prepare the Vehicle
Start by parking the Lexus IS on a flat surface. Engage the parking brake and loosen the lug nuts on the wheels without removing them completely. Then, lift the vehicle using a jack and secure it with jack stands.
Step 2: Remove the Existing Struts
Remove the wheels and locate the strut assembly. Use penetrating oil on the bolts to make removal easier. Unbolt the strut from the steering knuckle and detach it from the upper strut mount. Carefully remove the strut from the vehicle.
Step 3: Install the Adjustable Coilovers
Using spring compressors, remove the spring from the factory strut and install it onto the adjustable coilover. Ensure everything is tightened properly. Position the coilover in place, securing it to the steering knuckle and upper mount. Repeat for the other side.
Step 4: Adjust the Ride Height
Once both coilovers are installed, adjust the ride height to your preference. Make sure to measure from the ground to the fender for consistency. Tighten all bolts to the manufacturer’s specifications.
Installing Sway Bars
Sway bars help reduce body roll during cornering, improving overall stability. Here’s how to install them on your Lexus IS.
Step 1: Remove the Old Sway Bars
Locate the sway bar and its mounting points. Unbolt the end links and the brackets securing the sway bar to the chassis. Remove the old sway bar from the vehicle.
Step 2: Install the New Sway Bars
Position the new sway bar in place and attach it to the mounting points. Secure the end links to the sway bar and tighten all bolts to the specified torque settings.
Step 3: Double-Check Everything
Before lowering the vehicle, double-check all bolts and connections. Ensure everything is tightened and secure. Reinstall the wheels and lower the vehicle back to the ground.
Testing Your Modifications
After installation, it’s crucial to test the modifications. Take the Lexus IS for a test drive, paying attention to handling and ride comfort. Make any necessary adjustments to the coilovers based on your driving experience.
Conclusion
Upgrading to adjustable coilovers and sway bars can dramatically enhance the performance of your Lexus IS. With improved handling and a customizable ride, these modifications are worth the investment for any enthusiast. Follow the steps outlined above for a successful installation and enjoy your enhanced driving experience.
