The E39 M5 is a remarkable vehicle that combines power and luxury. However, to enhance its handling and overall performance, many enthusiasts opt for upgrades such as adjustable sway bars, strut bars, and bushings. This guide will walk you through the installation process of these components to improve your M5’s handling characteristics.
Why Upgrade Your Handling Components?
Upgrading the handling components of your E39 M5 can lead to improved stability, cornering performance, and overall driving enjoyment. Here are some benefits:
- Improved Cornering: Adjustable sway bars allow for better weight distribution during turns.
- Enhanced Stability: Strut bars increase chassis rigidity, reducing body roll.
- Better Response: Upgraded bushings provide a more direct connection between the suspension and chassis.
Tools and Materials Needed
Before starting the installation, ensure you have the following tools and materials on hand:
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Adjustable sway bars
- Strut bars
- Bushings
- Grease
Step-by-Step Installation Guide
1. Preparing the Vehicle
Begin by parking your E39 M5 on a flat surface and engaging the parking brake. Use a jack to lift the front of the vehicle and secure it with jack stands. This will provide you with sufficient access to the suspension components.
2. Removing the Old Components
To install the new components, you must first remove the old sway bars, strut bars, and bushings:
- Locate the sway bar and remove the end links using a socket wrench.
- Unbolt the sway bar from the chassis and remove it from the vehicle.
- Next, remove the strut bar by loosening the bolts that secure it to the strut towers.
- Finally, replace the bushings by unbolting the suspension components and removing the old bushings.
3. Installing Adjustable Sway Bars
Once the old sway bar is removed, follow these steps to install the adjustable sway bars:
- Position the new adjustable sway bar in place of the old one.
- Secure it to the chassis using the provided bolts, ensuring they are torqued to the manufacturer’s specifications.
- Attach the end links to the sway bar and tighten them securely.
- Adjust the sway bar settings as per your desired stiffness.
4. Installing Strut Bars
With the sway bar installed, you can now proceed to install the strut bars:
- Align the strut bar with the strut towers and secure it with the provided bolts.
- Tighten the bolts to the specified torque settings to ensure proper fitment.
- Check for any clearance issues before finalizing the installation.
5. Replacing Bushings
Finally, replace the old bushings with new ones:
- Apply grease to the new bushings to facilitate installation.
- Position the new bushings in the suspension components and reassemble everything.
- Torque all bolts to the manufacturer’s specifications to ensure everything is secure.
Final Checks and Testing
After completing the installation, it is crucial to perform a few final checks:
- Double-check all bolts and connections for tightness.
- Lower the vehicle and remove the jack stands.
- Take the M5 for a test drive to assess the handling improvements.
Conclusion
Upgrading the handling components of your E39 M5 can significantly enhance your driving experience. By following this guide, you can successfully install adjustable sway bars, strut bars, and bushings, leading to improved performance and handling. Enjoy your enhanced ride!
