The BRZ has become a popular platform for drift enthusiasts due to its lightweight chassis and rear-wheel-drive layout. One of the most critical components in a drift build is the differential, which plays a significant role in how the car behaves during aggressive drifts. In this article, we will explore how to set up your differential for optimal drifting performance.
Understanding Differentials
A differential allows the wheels to rotate at different speeds, which is essential for cornering. In a drift scenario, however, you want the rear wheels to spin at the same rate to maintain control and achieve the desired slide. This is where a limited-slip differential (LSD) comes into play.
Types of Differentials
- Open Differential: The standard setup that allows wheels to spin independently. Not ideal for drifting.
- Limited-Slip Differential (LSD): Provides better traction by limiting the difference in wheel speed.
- Locking Differential: Locks both wheels together for maximum traction but can be difficult to control.
Choosing the Right Differential for Your BRZ
When selecting a differential for your BRZ drift build, consider the following factors:
- Driving Style: Your approach to drifting will influence the type of differential you need.
- Budget: Differentials can vary widely in price, so choose one that fits your financial plan.
- Durability: Ensure the differential can withstand the stresses of aggressive drifting.
Installing a Limited-Slip Differential
Installing an LSD in your BRZ is a critical step in enhancing your drift capabilities. Here’s a step-by-step guide:
- Gather Tools: You’ll need basic hand tools, a jack, and jack stands.
- Remove the Rear Axle: Safely lift the car and remove the rear axle to access the differential.
- Drain the Differential Oil: Use a drain pan to catch the old oil.
- Remove the Old Differential: Unbolt and take out the existing differential.
- Install the New LSD: Follow the manufacturer’s instructions for proper installation.
- Reassemble: Put everything back together, ensuring all bolts are tightened to specifications.
- Refill Differential Oil: Use the recommended oil type for your new LSD.
Setting Up the Differential for Drifting
Once your LSD is installed, you need to set it up for optimal performance. This includes adjusting the preload and the type of LSD you have.
- Preload Adjustment: Adjusting the preload can help with how quickly the differential engages during a drift.
- Clutch Type vs. Gear Type: Choose between clutch-type LSDs for better control or gear-type for more aggressive setups.
Testing Your Setup
After installation and setup, it’s crucial to test your differential in a controlled environment. Here’s how to do it:
- Find a Safe Location: Look for an empty parking lot or a drift track.
- Start Slow: Begin with gentle throttle inputs to assess how the differential behaves.
- Progressively Increase Speed: As you gain confidence, increase your speed and angle during drifts.
- Make Adjustments: If necessary, make further adjustments to the differential setup based on your testing.
Common Issues and Troubleshooting
Even with the best setup, you may encounter some issues. Here are common problems and their solutions:
- Wheel Hop: This can occur if the differential is too tight. Adjust the preload to alleviate this issue.
- Uneven Tire Wear: Check your alignment and ensure the differential is functioning properly.
- Noise from the Differential: Ensure that the installation was done correctly and that all components are lubricated.
Conclusion
Setting up your differential for drifting in a BRZ is a vital step for achieving aggressive and controlled drifts. By understanding the types of differentials, selecting the right one, and properly installing and adjusting it, you can significantly enhance your drift performance. Remember to test your setup and make necessary adjustments to ensure the best results. Happy drifting!
