The BMW E39 M5 is a legendary performance sedan, known for its powerful V8 engine and superb handling. However, many enthusiasts seek to enhance its handling characteristics without incurring exorbitant costs. This article explores several cost-effective modifications that can significantly improve the handling of the E39 M5.
1. Upgrade the Suspension Components
One of the most impactful ways to improve handling is by upgrading suspension components. Here are some budget-friendly options:
- Lowering Springs: Replacing factory springs with lowering springs can reduce body roll and improve cornering stability.
- Shock Absorbers: Consider upgrading to high-performance shock absorbers for better control and responsiveness.
- Sway Bars: Installing thicker sway bars can minimize body roll during turns, enhancing overall handling.
2. Enhance Tire Performance
Tires are the only contact point between your vehicle and the road. Investing in quality tires can dramatically improve handling. Consider the following:
- Performance Tires: Opt for high-performance tires that offer better grip and responsiveness.
- Tire Pressure Monitoring: Regularly check and maintain proper tire pressure for optimal performance.
- Tire Rotation: Rotate your tires regularly to ensure even wear and prolong their lifespan.
3. Improve Alignment and Geometry
Proper alignment is crucial for maximizing handling performance. Consider the following adjustments:
- Wheel Alignment: Get a professional alignment to ensure that your wheels are correctly positioned.
- Camber Adjustment: Adjusting camber angles can enhance cornering grip.
- Toe Settings: Fine-tuning toe settings can improve steering response and stability.
4. Upgrade Bushings
Worn or soft bushings can lead to a lack of responsiveness in handling. Upgrading to stiffer bushings can provide a more connected feel to the road. Options include:
- Control Arm Bushings: Replace the factory bushings with polyurethane options for improved stiffness.
- Subframe Bushings: Upgrading subframe bushings can reduce flex and enhance chassis rigidity.
- Sway Bar Bushings: Stiffer sway bar bushings can improve the effectiveness of your sway bars.
5. Lightweight Wheels
Switching to lightweight wheels can reduce unsprung weight, improving handling and responsiveness. Consider the following:
- Material Options: Look for wheels made from lightweight alloys or forged materials.
- Size Considerations: Choose the right size to maintain the correct fitment and avoid compromising ride quality.
- Design: Opt for designs that enhance airflow to brakes, improving cooling and performance.
6. Brake Upgrades
Improving braking performance can enhance your confidence in handling. Here are some cost-effective brake upgrades:
- Brake Pads: Upgrade to performance brake pads that offer better grip and fade resistance.
- Brake Lines: Consider stainless steel brake lines for improved pedal feel and response.
- Brake Fluid: Use high-temperature brake fluid to prevent fade during spirited driving.
7. Weight Reduction
Reducing overall weight can improve handling and acceleration. Here are some strategies:
- Remove Unnecessary Items: Clear out any non-essential items from the trunk and interior.
- Lightweight Components: Consider replacing heavy factory parts with lighter alternatives.
- Carbon Fiber Parts: If budget allows, look into carbon fiber components for significant weight savings.
8. Driving Technique
Sometimes, the best modifications are not mechanical but rather improvements in driving technique. Consider the following tips:
- Practice Smooth Inputs: Make smooth steering, throttle, and brake inputs for better control.
- Learn Cornering Techniques: Understand the principles of cornering to maximize grip and minimize understeer.
- Participate in Track Days: Gain experience and improve your skills by attending track events.
Conclusion
Enhancing the handling of your E39 M5 doesn’t have to break the bank. By implementing these cost-effective modifications, you can experience significant improvements in performance and enjoyment behind the wheel. Whether you’re a weekend warrior or a daily driver, these upgrades will make your M5 more responsive and fun to drive.
