Preparation
Before you start the installation, it’s essential to prepare your workspace and gather all necessary tools and materials. Ensure your vehicle is parked on a level surface and that you have enough room to work around it.
Put on your safety glasses and gloves to protect yourself during the installation process.
Step 1: Lifting the Vehicle
Using a jack, lift the front or rear of your Lexus IS300, depending on which coilovers you are installing first. Secure the vehicle with jack stands to ensure safety while you work.
Step 2: Removing the Old Suspension
Start by removing the wheels to access the suspension components. Use your socket set to remove the lug nuts and set the wheels aside.
Next, locate the upper and lower mounting points of the existing struts. You may need to apply penetrating oil to loosen any rusted bolts.
Remove the bolts securing the lower strut mount first, then move to the upper mount. Carefully detach the strut from the vehicle.
Step 3: Preparing the HKS Coilovers
Before installation, prepare your HKS Hyper Max Coilovers. If your coilovers come with adjustable settings, set them to the desired height according to your preference.
Step 4: Installing the HKS Coilovers
Begin by inserting the HKS coilover into the lower mount location. Secure it with the bolts you removed earlier. Make sure to tighten them to the manufacturer’s specifications using a torque wrench.
Next, attach the upper mount of the coilover to the vehicle. Again, ensure all bolts are tightened properly.
Step 5: Reinstalling the Wheels
Once the coilovers are securely installed, it’s time to put the wheels back on. Align the wheel with the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then use your torque wrench to tighten the lug nuts to the proper specifications.
Step 6: Adjusting the Coilovers
After installation, it’s crucial to adjust your coilovers to achieve the desired ride height and suspension stiffness. Refer to the HKS manual for specific adjustment instructions.
Step 7: Test Drive and Final Checks
Once everything is installed and adjusted, take your Lexus IS300 for a test drive. Pay attention to how the vehicle handles and listen for any unusual noises.
After the test drive, recheck all bolts and adjustments to ensure everything is secure and functioning correctly.
Conclusion
Installing HKS Hyper Max Coilovers on your Lexus IS300 can transform your driving experience. By following this step-by-step guide, you can achieve a successful installation and enjoy improved handling and ride quality.
