Installing H&R lowering springs on your Audi RS7 can enhance its performance and appearance. This guide provides a detailed step-by-step process along with a cost breakdown to help you through the installation.
Tools and Materials Needed
- H&R Lowering Springs
- Jack and jack stands
- Socket set
- Torque wrench
- Spring compressor
- Safety glasses
- Gloves
Before you begin, ensure you have all the necessary tools and materials. Safety is paramount, so wear gloves and safety glasses throughout the installation process.
Step 1: Prepare Your Vehicle
Start by parking your Audi RS7 on a flat surface. Engage the parking brake and loosen the lug nuts on the front wheels while the vehicle is still on the ground.
Next, use the jack to lift the front of the vehicle and secure it with jack stands. Make sure the vehicle is stable before proceeding.
Step 2: Remove the Front Wheels
Once the vehicle is securely lifted, remove the lug nuts and take off the front wheels. This will give you access to the suspension components.
Step 3: Remove the Strut Assembly
To remove the strut assembly, locate the upper strut mount under the hood. Remove the nuts securing the strut mount using a socket wrench.
Next, detach the lower end of the strut from the steering knuckle. You may need to use a ball joint separator for this step. Ensure that all bolts are removed and set them aside for reinstallation.
Step 4: Install the Spring Compressor
With the strut assembly removed, use a spring compressor to safely compress the spring. This is crucial for removing the spring from the strut without causing injury.
Step 5: Replace the Springs
Once the spring is compressed, remove the top strut nut and take off the old spring. Carefully place the H&R lowering spring onto the strut and reattach the top nut. Make sure to follow the manufacturer’s specifications for torque settings.
Step 6: Reassemble the Strut
After installing the new springs, decompress the spring compressor. Ensure everything is aligned properly and reattach the strut assembly to the vehicle. Start by securing the lower end of the strut to the steering knuckle.
Step 7: Reinstall the Front Wheels
With the strut assembly back in place, reinstall the front wheels. Hand-tighten the lug nuts to secure the wheels before lowering the vehicle back to the ground.
Step 8: Lower the Vehicle and Torque the Lug Nuts
Carefully lower the vehicle off the jack stands. Once the car is on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
Step 9: Repeat for the Rear Springs
Follow similar steps for the rear springs. Lift the rear of the vehicle, remove the rear wheels, and detach the rear strut assembly. Replace the springs and reassemble everything as you did for the front.
Cost Breakdown
Here’s a rough estimate of the costs associated with installing H&R lowering springs on your RS7:
- H&R Lowering Springs: $300 – $400
- Tools (if not owned): $100 – $200
- Labor (if using a shop): $200 – $300
- Total Estimated Cost: $600 – $900
