BMW M2 Competition F87 Maintenance Guide
BMW M2 F87 S55 Maintenance Guide
The BMW M2 F87 with the S55 engine, also known as the "M2 Competition" or "M2 Comp," is a high-performance variant of the M2 series. Equipped with the 3.0-litre twin-turbocharged inline-six S55 engine, it delivers impressive power and handling, making it a popular choice for performance enthusiasts and track drivers. However, as with any high-performance vehicle, it is crucial to maintain the M2 Comp properly, especially if it has been used on track.
This maintenance guide provides an overview of key maintenance tasks and considerations for the M2 Competition S55, focusing on the needs of owners who may be driving their M2 Competition on both the road and track.
Regular Maintenance Intervals
Routine maintenance is essential to keeping the M2 F87 S55 in peak condition. Adhering to the manufacturer’s recommended intervals ensures the car operates reliably, even under demanding conditions.
Engine Oil and Oil Filter Change: For optimal engine performance, the oil and oil filter should be changed every 10,000 miles (16,000 km) or annually, whichever comes first. If the car is used on track frequently, you may want to change the oil more often to prevent contaminants and maintain engine longevity. Check out our M2 Competition service parts here.
Brake Fluid: Brake fluid should be replaced every 2 years (approximately 24,000 miles or 38,500 km) to maintain proper braking performance. For track use, it’s essential to monitor brake fluid levels more regularly, as the high temperatures generated under heavy braking can degrade the fluid more quickly. Consider changing your brake fluid to a more suitable RBF660.
Air Filter: The air filter should be replaced every 30,000 miles (48,000 km) under normal conditions, but more frequent changes may be required if the car is driven on dusty roads or used for track days. A clean air filter ensures optimal airflow to the engine, improving performance and fuel efficiency.
A lot of owners opt for aftermarket intakes for the sake of sound, air-flow or both! If you would prefer an aftermarket kit, check out our options here.
Coolant: The coolant should be replaced every 2 years (24,000 miles or 38,500 km) to ensure the engine runs at the correct temperature. If the car is subjected to high-performance use, particularly on track, you may want to check the coolant level regularly and ensure the system is in good working order.
Track-Oriented Maintenance
The M2 Comp is a performance car built for spirited driving and track use. If you plan to take your M2 F87 S55 to the track, it’s important to pay special attention to several areas that may experience increased wear under these conditions.
Tyre Wear and Alignment: Track use places extra strain on tyres, particularly around the inner edges. If you notice uneven or excessive inner tyre wear, it could indicate poor alignment or aggressive driving. Be sure to check the alignment regularly and replace tyres when tread depth reaches 3mm or less. Additionally, high-performance tyres should be inspected for cracks, bulges, or any other signs of damage before and after track use.
Brakes: High-performance driving on the track can lead to faster brake wear. The brake pads and discs should be inspected frequently for signs of wear, especially if you use the M2 Comp for track days. Track-focused brake pads and fluids are often recommended to handle the higher temperatures generated during heavy braking. If you notice any decrease in braking performance, or if the brake pads are worn down, replace them promptly. Have you cooked your brakes? Looking for an upgrade?

Suspension and Chassis Play: The M2 F87’s suspension is tuned for precision handling, but track driving can accelerate wear on components like bushings, control arms, and dampers. Look out for any unusual play or movement in the suspension during cornering or braking. Chassis play or knocking sounds can indicate worn suspension components. Ensure the suspension is properly aligned, and consider upgrading the suspension components for improved durability if you use the M2 Comp on track regularly.
Transmission and Differential Fluids: High-performance driving generates additional heat and stress on the drivetrain. It’s recommended to check the transmission and differential fluids every 30,000-40,000 miles (48,000-64,000 km) to ensure the components are properly lubricated. If you’re using the car extensively on track, consider changing the fluids more frequently to maintain smooth operation and prevent premature wear.
Engine and Drivetrain Health
While the S55 engine is known for its performance and reliability, it is crucial to monitor the health of the engine and drivetrain to ensure the car continues to perform at its best, especially if it’s used on track.
Oil and Cooling Systems: The S55 engine requires clean oil for optimal performance. Regular oil changes and checks for leaks are essential, particularly if the car is used hard on track. Pay attention to oil temperatures; elevated oil temperatures during track use can indicate potential issues with the cooling system. Ensure that the radiator, intercooler, and cooling pipes are all functioning properly and free from leaks or cracks.
Boost Pressure and Turbo Health: The S55 engine is turbocharged, which means it’s crucial to monitor the turbocharger’s health, particularly if the car has been used extensively for performance driving. Listen for any unusual noises such as whistling or whining, which could indicate problems with the turbo system. Regularly check for any boost leaks or damaged hoses, as these can affect engine performance.
Clutch and Gearbox: If you have a manual transmission M2 Comp, check the clutch for signs of wear, especially if the car has been used for aggressive driving or track days. A slipping clutch or difficulty engaging gears can signal the need for replacement. For those with the DCT gearbox, ensure that the gear shifts are smooth and responsive; any hesitation or jerking could point to an issue with the transmission.
General Wear and Tear
As with any used car, general wear and tear will occur over time. Some areas of the M2 F87 S55 may need more attention depending on the usage history.
Suspension Components: Besides checking for chassis play, ensure that suspension components like bushings, dampers, and anti-roll bars are in good condition. These parts can wear out more quickly if the car has been heavily driven on rough roads or on the track. Replacing worn-out suspension components ensures that the car maintains its sharp handling characteristics.
Battery Health: The M2 F87’s battery should be checked regularly, especially if the car is often used in high-performance environments. Performance driving places a significant load on the electrical system, so make sure the battery is properly charged and in good condition. If the battery is more than 4-5 years old, consider replacing it to avoid unexpected failure.
Modifications for Track Use
If you regularly take your M2 Comp to the track, several upgrades can enhance performance and durability:
Performance Brake Pads: Track-specific brake pads can provide better heat resistance and stopping power under high-performance conditions. These pads can withstand the increased temperatures generated during track use without compromising performance.
Suspension Upgrades: Upgrading to adjustable coilovers, reinforced bushings, or upgraded anti-roll bars can help the M2 Comp handle better under track conditions. These upgrades provide more control and durability under stress.
Cooling Enhancements: Consider adding an upgraded intercooler, radiator, or oil cooler to improve the car’s cooling efficiency during track use. These enhancements will prevent the engine and turbo system from overheating, particularly during extended track sessions.
Conclusion
Maintaining the BMW M2 F87 S55 (M2 Competition) requires careful attention, particularly if you plan to use it for performance driving or track days. Regular maintenance is essential to keep the engine, drivetrain, and suspension in top condition, while track-specific checks on tyres, brakes, and suspension components are crucial to maintaining performance and safety.
By staying on top of routine maintenance and addressing track-specific wear early, you can ensure that your M2 Comp continues to deliver exceptional driving experiences for years to come. Whether you’re a daily driver or a track enthusiast, proper maintenance will help you preserve the car’s performance and reliability.
