The BMW M240i is a powerful compact coupe that combines luxury and performance. With its 365 horsepower engine, it provides an exhilarating driving experience. However, to truly maximize its potential, performance upgrades are essential. One of the most effective upgrades is the installation of a reinforced differential, which significantly enhances handling and traction.
Understanding the Importance of a Reinforced Differential
A differential is a crucial component in any vehicle, allowing the wheels to rotate at different speeds, especially during turns. The M240i is equipped with a standard differential, but for those looking to push their car to the limits, a reinforced differential offers several advantages:
- Improved Traction: A reinforced differential provides better power distribution to the wheels, reducing wheel spin and improving grip on various surfaces.
- Enhanced Stability: It helps maintain stability during aggressive cornering, allowing for more confidence-inspiring handling.
- Increased Durability: Reinforced differentials are designed to withstand higher torque loads, making them ideal for modified engines.
Choosing the Right Reinforced Differential
When selecting a reinforced differential for your BMW M240i, consider the following factors:
- Type of Differential: Options include limited-slip differentials (LSD) and torque vectoring differentials. Each has its benefits depending on driving style.
- Brand Reputation: Look for reputable brands known for quality and performance, such as Quaife or Wavetrac.
- Compatibility: Ensure the differential is compatible with the M240i’s specifications and your performance goals.
Installation Process of a Reinforced Differential
Installing a reinforced differential requires technical knowledge and the right tools. Here’s a step-by-step guide to help you through the process:
Tools and Materials Needed
- Jack and jack stands
- Socket set
- Torque wrench
- Differential fluid
- Reinforced differential unit
- Gasket and sealant
Step-by-Step Installation
- Prepare the Vehicle: Park the M240i on a level surface, engage the parking brake, and lift the rear of the car using a jack and secure it with jack stands.
- Remove the Rear Differential Cover: Use a socket set to remove the bolts securing the differential cover. Drain the old fluid into a container.
- Remove the Old Differential: Disconnect any components attached to the differential, including the driveshaft, and remove the old unit.
- Install the Reinforced Differential: Place the new reinforced differential in position and secure it according to the manufacturer’s specifications.
- Reattach Components: Reconnect the driveshaft and any other components you removed earlier.
- Replace the Differential Cover: Apply a new gasket and sealant, then reattach the differential cover and torque the bolts to the specified settings.
- Fill with Differential Fluid: Refill the differential with the appropriate fluid, ensuring it meets BMW specifications.
Testing Your BMW M240i After Installation
After installing the reinforced differential, it’s crucial to test your BMW M240i to ensure everything is functioning correctly. Here are some tips for testing:
- Initial Drive: Take the car for a short drive, paying attention to any unusual noises or vibrations.
- Handling Check: Test the handling by taking corners at various speeds to assess improvements in traction and stability.
- Fluid Check: After a few drives, check the differential fluid level and look for any leaks around the differential cover.
Conclusion
Upgrading to a reinforced differential is one of the best performance enhancements you can make for your BMW M240i. With improved traction, stability, and durability, you’ll experience a more exhilarating driving experience at 365 horsepower. Follow the installation guide carefully, and enjoy the enhanced performance of your upgraded M240i.
