Preparation Steps

Before starting the installation, ensure you have a clean workspace and all necessary tools at hand. Follow these preparation steps:

  • Park your Audi RS5 on a flat surface.
  • Engage the parking brake.
  • Wear safety glasses and gloves for protection.

Step 1: Lifting the Vehicle

To access the suspension components, lift the vehicle using a jack and secure it with jack stands. Follow these steps:

  • Locate the jacking points on your Audi RS5.
  • Use the jack to lift the vehicle until it is high enough to work underneath.
  • Place jack stands under the vehicle for safety.

Step 2: Removing the Front Struts

To install the lowering springs, you must first remove the front struts. Follow these sub-steps:

  • Remove the wheel by loosening the lug nuts and taking off the wheel.
  • Disconnect the brake line bracket from the strut.
  • Unbolt the strut from the steering knuckle.
  • Remove the top strut mount bolts from the engine bay.
  • Carefully pull the strut out of the wheel well.

Using a Spring Compressor

Once the strut is removed, use a spring compressor to safely remove the factory spring:

  • Place the strut in a spring compressor.
  • Compress the spring evenly on both sides.
  • Remove the top strut mount and then the spring.

Step 3: Installing H&R Lowering Springs

With the factory spring removed, it’s time to install the H&R lowering springs:

  • Place the H&R lowering spring onto the strut.
  • Reinstall the top strut mount.
  • Ensure everything is aligned correctly.

Step 4: Reinstalling the Front Struts

After installing the lowering springs, you can reinstall the struts into the vehicle:

  • Carefully position the strut back into the wheel well.
  • Secure the top strut mount bolts in the engine bay.
  • Reattach the strut to the steering knuckle.
  • Reconnect the brake line bracket.
  • Replace the wheel and tighten the lug nuts.

Step 5: Removing the Rear Springs

Now, proceed to the rear springs. Follow these steps:

  • Remove the rear wheels.
  • Unbolt the rear struts from the lower control arm.
  • Remove the top bolts from the strut in the trunk.
  • Carefully pull the strut out.

Using a Spring Compressor for Rear Springs

Just like the front, use a spring compressor for the rear springs:

  • Place the rear strut in the spring compressor.
  • Compress the spring evenly.
  • Remove the top mount and then the spring.

Step 6: Installing H&R Lowering Springs on the Rear

Install the H&R lowering springs on the rear struts:

  • Place the H&R spring onto the rear strut.
  • Reattach the top mount.
  • Ensure everything is aligned properly.

Step 7: Reinstalling the Rear Struts

Now, reinstall the rear struts back into the vehicle:

  • Position the strut back into the wheel well.
  • Secure the top bolts in the trunk.
  • Attach the strut to the lower control arm.
  • Replace the rear wheels and tighten the lug nuts.

Step 8: Final Checks and Lowering the Vehicle

With the springs installed, it’s time to lower the vehicle and perform final checks:

  • Remove the jack stands and lower the vehicle with the jack.
  • Check the alignment of the wheels.
  • Torque all bolts to the manufacturer specifications.
  • Take the vehicle for a test drive to ensure everything is functioning correctly.

Conclusion
