by

The BMW M4 is a high-performance sports car that offers an exhilarating driving experience. However, to maximize its handling capabilities, many enthusiasts consider upgrading their suspension and tire setup. In this guide, we will explore the installation of coilovers, sway bars, and performance tires to enhance the handling of your BMW M4.

Understanding the Basics of Suspension Upgrades

Before diving into the specifics of coilovers, sway bars, and performance tires, it’s essential to understand why these components are crucial for improving handling. Upgrading your suspension can lead to better cornering, reduced body roll, and enhanced overall stability.

What Are Coilovers?

Coilovers are a type of suspension system that combines a coil spring and shock absorber into a single unit. They allow for adjustable ride height and damping settings, giving drivers the ability to customize their vehicle’s handling characteristics.

Benefits of Installing Coilovers

  • Improved handling and cornering capability.
  • Lowered ride height for a more aggressive stance.
  • Adjustable damping for personalized driving preferences.
  • Enhanced stability during high-speed maneuvers.

Installing coilovers can significantly improve the handling of your BMW M4. Here’s a step-by-step guide to help you through the installation process.

Tools and Materials Needed

  • Coilover kit specific to BMW M4
  • Jack and jack stands
  • Socket set and wrenches
  • Torque wrench
  • Spring compressor (if necessary)

Step-by-Step Installation Process

  • Park your BMW M4 on a flat surface and engage the parking brake.
  • Loosen the lug nuts on the wheels before lifting the car with a jack.
