Weight reduction is a critical aspect when it comes to enhancing the performance of a high-performance vehicle like the Nissan GT-R. One of the most effective ways to achieve this is by replacing the driveshaft with a carbon fiber alternative. This article will guide you step-by-step on how to install a carbon fiber driveshaft in your Nissan GT-R, providing insight into its benefits, the necessary tools, and the installation process.
Understanding the Benefits of a Carbon Fiber Driveshaft
Before diving into the installation process, it’s important to understand why a carbon fiber driveshaft is a worthy investment. Unlike traditional steel or aluminum driveshafts, carbon fiber driveshafts offer significant advantages.
Weight Reduction: Carbon fiber is significantly lighter than both steel and aluminum. This weight reduction translates into improved acceleration and handling. A lighter driveshaft reduces the overall weight of the car, which is especially beneficial for performance-focused vehicles like the Nissan GT-R.
Strength and Durability: Despite being lighter, carbon fiber is incredibly strong. This durability ensures that the driveshaft can handle the high torque and stress associated with the GT-R’s powerful engine without the risk of bending or breaking.
Reduced Vibration: Carbon fiber’s unique properties help in absorbing vibrations, resulting in a smoother and quieter driving experience. This reduction in vibration also contributes to less wear and tear on other drivetrain components.
Performance Improvements: The reduction in weight and vibration combined with the enhanced strength leads to noticeable improvements in the car’s overall performance. The GT-R will be more responsive and quicker off the line.
Essential Tools and Preparation for Installation
Tools You Will Need:
- Jack and jack stands
- Wrench set
- Socket set
- Torque wrench
- Thread locker
- Safety glasses and gloves
Preparation Steps:
- Safety First: Before beginning the installation, ensure the car is parked on a flat and stable surface. Use jack stands to properly lift and secure the vehicle. Safety glasses and gloves should be worn to protect from any debris or sharp edges.
- Locate the Driveshaft: The driveshaft in the Nissan GT-R connects the transmission to the rear differential. It runs along the underbody of the car and will need to be accessed from below.
- Disconnect the Battery: It is crucial to disconnect the car’s battery to prevent any accidental short circuits or electric shocks during the installation process.
Removing the Original Driveshaft
Removing the original driveshaft is a critical step in installing the new carbon fiber driveshaft. Follow these steps to ensure a smooth removal process:
- Loosen the Exhaust System: To gain better access to the driveshaft, you may need to loosen or remove sections of the exhaust system. This will involve unbolting the exhaust from its mounts and potentially removing the sway bars.
- Mark the Driveshaft Position: Use a marker to note the position of the original driveshaft. This will help you align the new carbon fiber driveshaft correctly.
- Remove the Bolts: Using a wrench and socket set, remove the bolts connecting the driveshaft to the rear differential and the transmission. Keep these bolts safe as you will need them for the installation of the new driveshaft.
- Support the Driveshaft: As you remove the bolts, support the driveshaft with one hand to prevent it from falling. Once all bolts are removed, carefully lower the driveshaft and set it aside.
Installing the Carbon Fiber Driveshaft
With the original driveshaft removed, you are now ready to install the new carbon fiber driveshaft. Follow these steps to ensure a successful installation:
- Inspect the New Driveshaft: Before installation, inspect the new carbon fiber driveshaft for any damage or defects. Ensure all components are included and in good condition.
- Align the Driveshaft: Align the carbon fiber driveshaft with the marks you made earlier. This will ensure it is positioned correctly and will function properly.
- Secure the Driveshaft: Using the original bolts, secure the carbon fiber driveshaft to the rear differential and the transmission. Apply thread locker to the bolts to prevent them from coming loose over time.
- Torque the Bolts: Use a torque wrench to tighten the bolts to the manufacturer’s specified torque settings. This step is crucial to ensure the driveshaft is securely attached and will not come loose during operation.
- Reattach the Exhaust System: Once the driveshaft is securely installed, reattach any sections of the exhaust system that were removed or loosened.
Final Checks and Adjustments
After the installation is complete, it is essential to perform some final checks and adjustments to ensure everything is functioning correctly:
- Double-Check the Bolts: Go over all the bolts once more to ensure they are properly tightened to the specified torque settings.
- Inspect for Clearance: Ensure there is adequate clearance between the driveshaft and other components such as the exhaust system and sway bars.
- Test the Driveshaft: Before taking the car for a drive, perform a few test rotations of the driveshaft by hand. This will help you identify any potential issues or misalignments.
- Reconnect the Battery: Once you are confident everything is in order, reconnect the car’s battery.
Installing a carbon fiber driveshaft in your Nissan GT-R is a worthwhile upgrade for any performance enthusiast looking to enhance their vehicle’s performance. The significant weight reduction, combined with the strength and durability of carbon fiber, results in noticeable improvements in acceleration, handling, and overall driving experience.
