Best Handling Upgrades for E90 M3: Improving Cornering and Responsiveness

by

The BMW E90 M3 is a performance-oriented vehicle that offers a thrilling driving experience. However, many enthusiasts look to enhance its handling capabilities further. Upgrading the suspension, tires, and other components can significantly improve cornering and responsiveness. In this article, we will explore the best handling upgrades for the E90 M3.

Suspension Upgrades

One of the most effective ways to improve the handling of your E90 M3 is through suspension upgrades. Here are some top options:

  • Coilovers: Upgrading to a quality set of coilovers allows for adjustable ride height and damping settings, resulting in better handling dynamics.
  • Anti-Roll Bars: Upgrading the front and rear anti-roll bars can reduce body roll during cornering, enhancing stability and grip.
  • Strut Braces: Adding strut braces can improve chassis rigidity, leading to better steering response and cornering performance.

Tire Upgrades

Tires are the only contact point between your car and the road. Upgrading your tires can dramatically affect handling. Consider the following:

  • Performance Tires: Opt for high-performance summer tires that offer better grip and responsiveness compared to standard tires.
  • Tire Width: Increasing the tire width can enhance traction and cornering stability, but be mindful of potential clearance issues.
  • Proper Alignment: After upgrading tires, ensure proper alignment to maximize handling performance.

Brake System Upgrades

Improving the braking system is essential for better handling, especially during aggressive driving. Here are some upgrades to consider:

  • Performance Brake Pads: Upgrading to high-friction brake pads can improve stopping power and reduce brake fade.
  • Slotted or Drilled Rotors: These rotors can help dissipate heat better, leading to improved braking performance during spirited driving.
  • Stainless Steel Brake Lines: These lines provide a firmer brake pedal feel and reduce the risk of brake line expansion under pressure.

Chassis and Weight Reduction

Reducing weight can significantly enhance the handling characteristics of your E90 M3. Consider these options:

  • Lightweight Wheels: Upgrading to lightweight wheels can reduce unsprung weight, improving responsiveness and acceleration.
  • Carbon Fiber Components: Replacing heavy components with carbon fiber alternatives can lower the overall weight of the vehicle.
  • Interior Removal: For track-focused builds, removing unnecessary interior components can further reduce weight and improve performance.

Engine and Drivetrain Enhancements

While the focus is primarily on handling, enhancing the engine and drivetrain can also contribute to improved responsiveness. Consider these upgrades:

  • Performance Air Intake: A high-flow air intake can improve engine responsiveness and throttle response.
  • ECU Tuning: A proper ECU tune can optimize performance and enhance throttle response, making the vehicle feel more agile.
  • Short Shifter: Installing a short shifter can provide quicker gear changes, improving driving engagement and responsiveness.

Conclusion

Upgrading the handling of your BMW E90 M3 can transform your driving experience. By focusing on suspension, tires, brakes, weight reduction, and engine enhancements, you can create a vehicle that is not only more responsive but also a joy to drive on both the road and the track. Choose the upgrades that best suit your driving style and enjoy the improved performance of your E90 M3.
