Step-by-Step Installation Guide
1. Prepare the Vehicle
Begin by parking the Lexus IS-F on a flat surface and ensuring the engine is off. Engage the parking brake and wear safety glasses and gloves for protection.
2. Lift the Vehicle
Using a jack, lift the front or rear of the vehicle, depending on which coilovers you are installing first. Secure the vehicle with jack stands to ensure stability.
3. Remove the Wheels
Using a socket set, remove the lug nuts and take off the wheels to access the suspension components.
4. Remove the Stock Coilovers
Locate the top and bottom mounting points of the stock coilover. Use the appropriate tools to remove the bolts securing the coilover in place. Carefully detach the coilover from the vehicle.
5. Install the KW Variant 3 Coilovers
Take the KW Variant 3 coilover and position it in the same location as the stock coilover. Secure it with the bolts you previously removed, ensuring they are tightened to the manufacturer’s specifications using a torque wrench.
6. Adjust Ride Height
Before reassembling everything, adjust the ride height to your desired level. This can be done using the adjustment collar on the coilover. Make sure to measure the height on both sides to maintain balance.
7. Reinstall the Wheels
Once the coilovers are installed, put the wheels back on and hand-tighten the lug nuts. Lower the vehicle back to the ground before fully tightening the lug nuts in a criss-cross pattern to ensure even pressure.
8. Repeat for the Other Side
Repeat the above steps for the other side of the vehicle, ensuring that both front and rear coilovers are installed correctly.
Final Adjustments and Testing
After all coilovers are installed, take the Lexus IS-F for a test drive to feel the difference. Pay attention to the handling and comfort levels. If necessary, make further adjustments to the damping settings to suit your driving style.
