Key Suspension Components to Upgrade
When considering suspension upgrades for the E36 M3, several components are worth focusing on. Each plays a vital role in the overall performance of the vehicle.
- Coilovers: Offers adjustable ride height and damping.
- Sway Bars: Reduces body roll during cornering.
- Strut Braces: Increases chassis rigidity.
- Bushings: Upgrading to polyurethane for better response.
Choosing the Right Coilovers
Coilovers are one of the most popular upgrades for the E36 M3. They provide a balance between performance and comfort. Here are some factors to consider when choosing coilovers:
- Damping Adjustment: Look for options that allow you to adjust compression and rebound.

- Warranty: Consider products with a good warranty for peace of mind.
Upgrading Sway Bars
Sway bars are essential for reducing body roll and improving cornering performance. Upgrading to larger sway bars can significantly enhance the handling characteristics of your E36 M3. Here are some tips for upgrading sway bars:
- Size Matters: Larger diameter bars provide more stiffness.
- Adjustability: Consider adjustable sway bars for tuning your setup.
- Material: Look for bars made from high-quality materials for durability.
Enhancing Chassis Rigidity with Strut Braces
Strut braces connect the upper strut towers, increasing chassis rigidity. This upgrade can enhance steering response and overall handling. Here’s what to look for:
- Material: Aluminum or steel options are common; choose based on weight and strength.
- Fitment: Ensure compatibility with your specific E36 M3 model.
- Installation: Most strut braces are easy to install with basic tools.
Upgrading Bushings for Better Response
Replacing stock rubber bushings with polyurethane bushings can improve handling and response. Polyurethane provides better feedback and is more durable. Consider these points:
- Performance: Improved stiffness without sacrificing comfort.
- Longevity: Polyurethane lasts longer than rubber.
- Installation: Some bushings may require professional installation.
Installation Tips and Considerations
Installing suspension upgrades can be a rewarding DIY project, but it’s essential to approach it with care. Here are some tips:
- Tools Required: Have the right tools, including a jack, jack stands, and wrenches.
- Alignment: Always get a professional alignment after suspension work.
- Take Your Time: Rushing can lead to mistakes; ensure everything is installed correctly.
Conclusion
Upgrading the suspension of your E36 M3 can dramatically enhance its handling and cornering confidence. By investing in quality components and taking the time to understand the options available, you can transform your driving experience. Whether you’re hitting the track or enjoying a spirited drive on winding roads, a well-tuned suspension will make all the difference.
