Building a Reliable F90 M5 Performance: Cooling, Oil, and Mounts for Daily and Track Use

by

The BMW F90 M5 is a powerhouse of performance, blending luxury with raw speed. However, to ensure that this high-performance sedan remains reliable both on the daily commute and during track days, it’s essential to focus on critical components such as cooling systems, oil management, and engine mounts. This article will delve into each of these areas, providing insights and recommendations for enhancing the reliability and performance of your F90 M5.

Cooling System Enhancements

The cooling system is vital for maintaining optimal engine temperatures, especially during spirited driving or track sessions. Upgrading the cooling system can prevent overheating and ensure consistent performance.

  • Upgraded Radiator: Consider installing a high-performance radiator designed to increase cooling efficiency. Look for models that offer improved airflow and larger capacity.
  • Oil Cooler: An aftermarket oil cooler can significantly reduce oil temperatures, which is crucial for engine longevity and performance under stress.
  • Enhanced Cooling Fans: Upgrading to high-flow electric fans can improve airflow through the radiator, especially in stop-and-go traffic or during track use.
  • Thermostat Upgrade: A lower temperature thermostat can help maintain cooler operating temperatures, which is beneficial for both daily driving and track conditions.

Oil Management Systems

Proper oil management is crucial for the performance and reliability of the F90 M5. High-quality oil and an effective oil management system will help keep the engine lubricated and cool.

  • High-Performance Engine Oil: Use a synthetic oil that meets or exceeds BMW’s specifications. Look for oils with high thermal stability and excellent lubrication properties.
  • Oil Filter Upgrade: An upgraded oil filter can improve filtration efficiency and oil flow, ensuring that your engine receives clean oil at all times.
  • Oil Catch Can: Installing an oil catch can can help prevent oil vapors from entering the intake system, which can lead to carbon buildup and decreased performance.
  • Oil Pan Baffle: Consider adding a baffle to the oil pan to prevent oil starvation during high-G cornering or acceleration, which can protect the engine during spirited driving.

Engine Mount Upgrades

Engine mounts play a critical role in how the vehicle handles and responds to driver inputs. Upgrading to performance mounts can enhance stability and reduce unwanted movement during aggressive driving.

  • Performance Engine Mounts: Consider aftermarket engine mounts that offer increased stiffness. These mounts can help reduce engine movement and improve throttle response.
  • Transmission Mounts: Upgrading transmission mounts can also help with shifting precision and reduce drivetrain slop, which is beneficial during track use.
  • Polyurethane Bushings: Replacing rubber bushings with polyurethane options can improve handling and responsiveness while providing durability.
  • Vibration Considerations: Keep in mind that stiffer mounts may introduce more vibration into the cabin, so choose mounts that balance performance and comfort based on your driving style.

Conclusion

Building a reliable F90 M5 for both daily and track use requires careful consideration of the cooling system, oil management, and engine mounts. By investing in high-quality upgrades in these areas, you can enhance the performance and longevity of your vehicle. Whether you’re navigating city streets or tackling a track day, these enhancements will ensure your F90 M5 remains a joy to drive, delivering power and precision when you need it most.
