The Infiniti G37 is a popular choice among car enthusiasts for its performance and handling. However, one of the key components that can significantly enhance its acceleration and cornering capabilities is the differential. Upgrading the differential can lead to improved power delivery and better traction, making your driving experience even more exhilarating.
Understanding the Differential
The differential is a crucial part of the drivetrain that allows the wheels to rotate at different speeds, especially during turns. In a performance car like the G37, a high-quality differential can greatly affect how power is transferred to the wheels. There are different types of differentials, each offering unique benefits.
Types of Differentials
- Open Differential: The standard type found in most vehicles, it allows for wheel speed differences but can limit traction.
- Limited-Slip Differential (LSD): Provides better traction by transferring power to the wheel with more grip.
- Locking Differential: Locks both wheels together for maximum traction in off-road or challenging conditions.
- Torque Vectoring Differential: Distributes torque between wheels independently for superior handling and cornering.
Benefits of Upgrading the Differential
Upgrading the differential in your Infiniti G37 can provide several key benefits:
- Improved Acceleration: A better differential enhances power transfer to the wheels, resulting in quicker acceleration.
- Enhanced Cornering: Upgraded differentials help maintain traction during turns, allowing for faster cornering speeds.
- Increased Stability: A high-performance differential can improve overall vehicle stability, especially during aggressive driving.
- Better Handling: Upgrades can lead to more responsive handling, making the car feel more connected to the road.
Choosing the Right Differential for Your G37
When selecting a differential for your Infiniti G37, consider the following factors:
- Driving Style: Determine if you prioritize acceleration, cornering, or a balance of both.
- Type of Use: Consider whether you will be using the car for daily driving, track days, or motorsports.
- Budget: Differentials can vary widely in price, so set a budget that aligns with your performance goals.
- Compatibility: Ensure the differential is compatible with your G37’s existing drivetrain components.
Popular Differential Upgrades for the G37
Here are some popular differential upgrades that G37 owners often consider:
- OEM Limited-Slip Differential: A direct replacement that offers improved traction over the stock open differential.
- Aftermarket LSD: Brands like Quaife and Nismo provide high-performance options that enhance grip and cornering.
- Torque Vectoring Systems: Advanced solutions that dynamically adjust power distribution for optimal performance.
- Custom Built Differentials: Tailored solutions for those seeking specific performance characteristics.
Installation Considerations
Installing a new differential can be a complex process. Here are some considerations:
- Professional Installation: It’s often best to have a professional handle the installation to ensure proper setup and alignment.
- Tools Required: Specialized tools may be necessary for the installation, including torque wrenches and bearing pullers.
- Break-in Period: After installation, a break-in period may be required to ensure optimal performance and longevity.
- Regular Maintenance: Keeping the differential in good condition with regular fluid changes is essential for performance.
Conclusion
Upgrading the differential in your Infiniti G37 can significantly enhance its acceleration and cornering capabilities. By understanding the different types of differentials and their benefits, you can make an informed decision that aligns with your driving style and performance goals. Whether you choose a limited-slip differential or a more advanced torque vectoring system, the right upgrade can transform your driving experience.
