Preparation
Before starting the installation, ensure that your Audi RS7 is parked on a flat, stable surface. Gather all necessary tools and materials, and wear safety gear, including gloves and goggles.
Step 1: Lift the Vehicle
Using the jack, lift the front of the vehicle and secure it with jack stands. Repeat this process for the rear of the car. Ensure the vehicle is stable before proceeding.
Step 2: Remove the Wheels
Using the socket set, remove the lug nuts from the front and rear wheels. Carefully take off the wheels and set them aside.

Step 3: Disconnect the Brake Line
Locate the brake line bracket on the strut assembly. Use a flathead screwdriver to gently pry it off and disconnect the brake line from the strut.
Step 4: Remove the Strut Assembly
Remove the top bolts of the strut assembly in the engine bay using a socket wrench. Then, unbolt the lower strut mount from the control arm. Carefully pull the strut assembly out of the wheel well.
Step 5: Remove the Rear Suspension
For the rear, locate the rear strut assembly. Remove the top bolts and lower bolts as you did with the front strut assembly. Carefully remove the rear strut from the vehicle.

Step 6: Prepare the Coilovers
Before installation, adjust the KW Variant 3 coilovers to your desired height settings. Make sure to follow the manufacturer’s instructions for optimal performance.
Step 7: Install the Front Coilovers
Insert the front coilover into the wheel well. Secure the lower mount to the control arm with the provided bolts. Reattach the top bolts in the engine bay, ensuring everything is tightened to the manufacturer’s specifications.
Step 8: Install the Rear Coilovers
For the rear, install the coilover by securing the lower mount to the control arm and the top mount in the trunk area. Again, ensure all bolts are tightened to the manufacturer’s specifications.
Final Steps
Step 9: Reinstall the Brake Lines
Reconnect the brake lines to the strut assemblies. Ensure they are secured in place with the brackets and that there is no interference with the coilovers.
Step 10: Reattach the Wheels
Place the wheels back onto the wheel hubs. Hand-tighten the lug nuts to secure them in place before lowering the vehicle.
Step 11: Lower the Vehicle
Carefully lower the vehicle back to the ground using the jack. Once on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
Post-Installation Checks
After installation, it is important to perform a few checks to ensure everything is secure and functioning correctly.
Step 12: Inspect the Installation
Check all bolts and connections for tightness. Make sure there are no leaks in the brake lines and that the coilovers are properly adjusted.
Step 13: Test Drive
Take your Audi RS7 for a test drive to assess the ride quality and handling. Listen for any unusual noises and check the suspension’s responsiveness.
