How Can You Retrofit an Electronic Limited-Slip Differential in a Rear-Wheel-Drive Infiniti G37?

If you’ve ever spun your car’s wheels in a high-torque situation or felt your car slipping in a tight turn, you may have wished for a better-drivetrain system. The electronic limited-slip differential (LSD) can be your answer. It’s a game-changing addition to your car that improves handling, stability, and the overall driving experience. In this article, we’ll guide you through the process of retrofitting your rear-wheel-drive Infiniti G37 with an LSD. We won’t just stop there, but look at the role of key components like the engine, braking, steering, suspension system, and wheel type in this upgrade.

Understanding the Importance of a Limited-Slip Differential

Before delving into the retrofitting process, let’s understand why an LSD can be a valuable addition to your car. The differential is a component in your drivetrain system located at the front or rear axle, depending on your car’s drive type. It balances the torque and rotational speed between the left and right wheels, ensuring smoother turns and improved traction.

However, a conventional open differential can cause problems on slippery surfaces or during high-speed manoeuvres. This is where the LSD steps in. An LSD, particularly an electronic one, provides better handling by distributing torque to the wheel with the most grip. As a result, it prevents wheel spin and improves your car’s performance in challenging situations.

Identifying the Components Needed for Retrofitting

Retrofitting an LSD in your rear-wheel-drive Infiniti G37 involves a few key components. It’s important to understand these components to successfully navigate through the retrofit process.

Firstly, you’ll need your chosen LSD. The type of LSD is crucial to your car’s performance. For an Infiniti G37, an electronic LSD is recommended due to its adaptability and high performance on both dry and slippery surfaces.

The differential is connected to the drivetrain system, comprising components like the engine, transmission, driveshaft, and wheels. Therefore, you need to pay attention to these parts during the retrofitting process because the LSD will have a direct impact on them.

Retrofitting the Electronic Limited-Slip Differential

The retrofitting process begins with removing the existing differential. You’ll need to drain the differential oil, disconnect the driveshaft, and remove the axles and brake system.

Once the old differential is out, you can fit in the electronic LSD. The LSD installation process can be a complex task. It requires precision, especially when setting the gear backlash and differential bearing preload. Mistakes here can lead to noise, vibration, and poor performance.

After installing the LSD, remember to reconnect the brake system and the driveshaft. Before you put the differential cover back on, fill the LSD up with the correct type of differential oil.

Adjusting Other Car Components

Retrofitting your Infiniti G37 with an electronic LSD isn’t just about the differential itself. You also need to consider how this change will affect other components of your car.

The LSD will affect the distribution of torque from the engine to the wheels. Thus, you may need to adjust your engine control unit (ECU) to match the LSD’s performance. This will provide better throttle response and smoother power delivery.

Next, consider your car’s suspension. The LSD can help to improve handling, especially when cornering. But, to truly seize the LSD’s advantages, you may want to upgrade your suspension system to one that can handle the increased performance.

Finally, it’s crucial to consider the impact of the LSD on your braking and steering systems. The LSD will improve your car’s stability, which can affect how you brake and steer. Therefore, you need to adjust these systems to match the improved stability.

Reflecting on the Benefits

Retrofitting an electronic LSD in your Infiniti G37 isn’t just about improving performance. It’s about enhancing your driving experience. The LSD can make your car more responsive, offer better control, improve fuel efficiency, and enhance safety.

The process can seem overwhelming at first, with many components to consider. But with a clear understanding of how each piece interacts with the LSD, you can successfully retrofit your car for a smoother and more enjoyable drive.

Remember, retrofitting an electronic LSD involves precise work. If you’re not comfortable carrying out this retrofit yourself, consider getting professional help. It’s a sizable investment, but the enhanced driving experience will be worth it.

There’s no doubt that retrofitting an electronic LSD in your Infiniti G37 is a value-adding upgrade. It not only improves the car’s performance but also makes every drive more enjoyable.

Evaluating the Role of Other Vehicle Components

When retrofitting an electronic limited-slip differential into an Infiniti G37, it’s crucial to evaluate the role of other vehicle components and how they’re impacted. This includes the engine, braking, steering, suspension system and wheels.

An electronic LSD primarily interacts with your engine and drivetrain. The engine is responsible for generating torque, which the differential subsequently distributes. Given this, you may need to fine-tune your engine control unit (ECU) to better harmonize with the LSD’s functionality. This can result in a better throttle response and more consistent power delivery.

Another crucial component is the braking system. The LSD impacts the stability of your vehicle, which can, in turn, affect your braking behavior. To maintain an optimal braking performance, necessary adjustments must be made in accordance with the new differential.

Furthermore, steering directly relies on the differential to facilitate smoother turns. With an electronic LSD, the steering wheel response becomes more precise and consistent due to improved wheel traction. This can lead to a more controlled and safer driving experience.

The suspension system can also be significantly influenced by the LSD. The improved handling, particularly during cornering, can put more stress on the suspension. Therefore, installing a more robust suspension adjustable system might be necessary.

Finally, the type of wheels can also impact the LSD’s performance. High-performance wheels can better cater to the increased torque and stability provided by the LSD. Consider upgrading the existing wheels if they fail to handle the new performance parameters.

Conclusion: Embracing the Benefits and Making the Transition

Upgrading your Infiniti G37 with an electronic LSD is not just about achieving higher performance metrics. It’s about amplifying the overall driving experience. With an LSD, your vehicle will be more responsive, deliver better control, enhance fuel efficiency, and boost safety. In essence, retrofitting an electronic LSD can transform your Infiniti G37 into a high-performance machine.

Although the retrofitting process can seem daunting, it’s manageable with a clear understanding of the LSD’s role and its interplay with other car components. By recognizing how an LSD interacts with the engine, braking, steering and suspension systems, you can more effectively adapt these parts to complement the LSD’s benefits.

However, the retrofitting process does require precision and expertise. If you’re not comfortable with DIY, don’t hesitate to seek help from professionals. While it requires investment, the improved driving experience derived from an LSD-equipped Infiniti G37 will undoubtedly justify the cost.

Remember, retrofitting an electronic LSD isn’t just an upgrade — it’s a transformation. It’s about turning your Infiniti G37 from a conventional rear-wheel-drive car into a more capable, responsive, and safer vehicle. By retrofitting an LSD, every drive becomes more enjoyable and exhilarating, truly enhancing your driving experience.

Today, we’ve taken a deep dive into retrofitting an electronic LSD in your Infiniti G37 — why it’s desirable, the components involved, the benefits it offers, and how it can redefine your driving experience. So, are you ready to make the transition?
