The BMW M3 is renowned for its performance, but even the best can benefit from upgrades. One of the most effective ways to enhance handling is by installing adjustable coilovers and performance bushings. This article will guide you through the process, ensuring you achieve the best performance from your BMW M3.
Understanding Coilovers
Coilovers are a popular suspension upgrade that combines the spring and shock absorber into a single unit. They allow for adjustable ride height and damping settings, giving drivers the ability to tailor their vehicle’s handling characteristics to their preferences.
- Improved handling and cornering stability
- Customizable ride height for a personalized look
- Enhanced performance on both the street and track
Benefits of Performance Bushings
Performance bushings replace the factory rubber bushings with stiffer materials, reducing flex and improving responsiveness. This upgrade can significantly enhance steering feel and overall handling.
- Increased precision in steering response
- Reduced body roll during cornering
- Enhanced durability and lifespan compared to stock bushings
Preparing for Installation
Before starting the installation, gather all necessary tools and components. This ensures a smooth process without interruptions. Here’s what you will need:
- Adjustable coilovers
- Performance bushings
- Jack and jack stands
- Socket set and wrenches
- Torque wrench
- Lubricant for bushings
Step-by-Step Installation Guide
Removing the Stock Suspension
Begin by safely lifting the vehicle using a jack and securing it with jack stands. Remove the wheels to gain access to the suspension components.
Next, disconnect the stock suspension components:
- Remove the top mount bolts of the strut
- Disconnect the sway bar links
- Unbolt the lower control arm
- Remove the coil spring and shock assembly
Installing Adjustable Coilovers
With the stock suspension removed, it’s time to install the adjustable coilovers. Follow these steps:
- Install the new coilover assembly into the strut mount.
- Secure the bottom of the coilover to the lower control arm.
- Adjust the ride height to your desired setting.
- Reattach the sway bar links.
Replacing Performance Bushings
After installing the coilovers, it’s time to replace the bushings. Here’s how:
- Remove the old bushings from the control arms and subframe.
- Apply lubricant to the new performance bushings to ease installation.
- Press the new bushings into place using a bushing press or appropriate tool.
Final Adjustments and Testing
Once all components are installed, double-check all bolts and fasteners for proper torque settings. It’s crucial to ensure everything is secure before taking the car out for a test drive.
After the installation, take the BMW M3 for a test drive to evaluate the new handling characteristics. Pay attention to how the car feels during cornering and braking. Adjust the coilovers as needed to find the perfect setup.
Conclusion
Upgrading the suspension of your BMW M3 with adjustable coilovers and performance bushings can dramatically improve handling and driving experience. By following this guide, you can enhance your vehicle’s performance, making it more responsive and enjoyable to drive.
