The BMW G80 M3 is a high-performance vehicle that combines luxury with exceptional driving dynamics. To further enhance its handling capabilities, many enthusiasts consider upgrades such as a front strut brace and lowering springs. These modifications can significantly improve the car’s agility and stability, making it even more enjoyable to drive.
Understanding the Benefits of Upgrades
Before diving into the installation process, it’s important to understand the benefits of adding a front strut brace and lowering springs to your G80 M3.
- Improved Handling: A front strut brace enhances chassis rigidity, reducing body roll and improving cornering stability.
- Lower Center of Gravity: Lowering springs reduce the ride height, which lowers the center of gravity and enhances overall vehicle stability.
- Better Aesthetics: Lowering the car gives it a more aggressive stance, improving its visual appeal.
- Enhanced Steering Response: Both upgrades contribute to more precise steering feedback, making the driving experience more engaging.
Tools and Materials Needed
To successfully install a front strut brace and lowering springs, you will need the following tools and materials:
- Socket set
- Torque wrench
- Spring compressor
- Jack and jack stands
- Front strut brace kit
- Lowering springs kit
- Safety glasses and gloves
Step-by-Step Installation Guide
Preparing the Vehicle
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is turned off. Follow these steps to prepare your G80 M3:
- Gather all tools and materials.
- Wear safety glasses and gloves for protection.

Installing the Front Strut Brace
The front strut brace installation is a straightforward process. Follow these steps:
- Locate the strut towers in the engine bay.
- Remove any covers that may obstruct access to the strut bolts.
- Loosen and remove the bolts securing the strut mounts.
- Position the front strut brace over the strut towers.
- Align the brace with the mounting holes and secure it with the provided bolts.
- Torque the bolts to the manufacturer’s specifications.
Installing Lowering Springs
Installing lowering springs requires more effort, as it involves disassembling the suspension. Follow these steps:
- Remove the front wheels to access the suspension components.
- Disconnect the sway bar links from the struts.
- Remove the brake calipers and hang them securely out of the way.
- Remove the strut assembly from the vehicle by loosening the bolts at the top and bottom.
- Use a spring compressor to safely compress the factory springs.
- Remove the top nut of the strut and take off the factory spring.
- Install the new lowering spring onto the strut.
- Reassemble the strut by securing the top nut and ensuring everything is tightened properly.
- Reinstall the strut assembly back into the vehicle and secure it with bolts.
- Reconnect the sway bar links and brake calipers.
- Repeat the process for the other side of the vehicle.
Post-Installation Checks
After completing the installation of the front strut brace and lowering springs, it’s crucial to perform some checks:
- Ensure all bolts and nuts are properly torqued to specification.
- Check that the strut brace is securely mounted and not interfering with any components.
- Inspect the suspension for any signs of wear or damage.
- Reinstall the front wheels and lower the vehicle back to the ground.
Conclusion
Upgrading your BMW G80 M3 with a front strut brace and lowering springs can lead to significant improvements in handling and performance. These modifications not only enhance driving dynamics but also contribute to a more aggressive appearance. With the right tools and a bit of patience, you can complete these upgrades and enjoy the benefits they bring to your driving experience.
