The Toyota AE86, a beloved icon among car enthusiasts, is known for its lightweight design and exceptional handling. One of the most significant upgrades you can make to enhance its performance is installing a limited-slip differential (LSD). This article will explore the costs, installation process, and the handling improvements that come with upgrading to an LSD.
Understanding Limited-Slip Differentials
A limited-slip differential is a type of differential that allows for some wheel slip while still providing power to both wheels. This is particularly beneficial in performance driving situations, where maintaining traction is crucial. The AE86, originally equipped with an open differential, can greatly benefit from the added traction and control that an LSD provides.
Benefits of Upgrading to an LSD
Upgrading to a limited-slip differential offers several advantages:
- Improved Traction: An LSD helps distribute power evenly to both wheels, reducing wheel spin during acceleration.
- Better Cornering: With enhanced grip, the AE86 can navigate corners more effectively, improving overall handling.
- Increased Stability: An LSD provides greater stability during high-speed maneuvers, making the car feel more planted.
- Enhanced Drifting Capability: For those interested in drifting, an LSD allows for easier control and smoother slides.
Cost of Upgrading to an LSD
The cost of upgrading to a limited-slip differential can vary based on several factors, including the type of LSD, brand, and whether you choose to install it yourself or hire a professional.
Types of Limited-Slip Differentials
There are mainly three types of LSDs available for the AE86:
- Clutch-type LSD: Offers excellent performance but may require more maintenance.
- Helical LSD: Provides smooth operation and is generally quieter, making it suitable for daily driving.
- Viscous LSD: Uses a fluid coupling mechanism and is less common but provides a good balance of performance and comfort.
Estimated Costs
Here’s a rough breakdown of the costs involved:
- Parts: $500 – $1,500 depending on the type and brand of LSD.
- Labor: $200 – $600 for professional installation.
- Total Estimated Cost: $700 – $2,100.
Installation Process
Installing a limited-slip differential in the AE86 can be a complex process, but with the right tools and knowledge, it can be done at home. Below is a general overview of the installation steps:
- Gather Tools and Parts: Ensure you have all necessary tools, including a jack, jack stands, wrenches, and the LSD kit.
- Remove the Rear Axle: Lift the car and remove the rear wheels, then disconnect the axle from the differential.
- Remove the Old Differential: Unbolt the old differential from the housing and carefully remove it.
- Install the New LSD: Place the new LSD into the differential housing, ensuring proper alignment.
- Reassemble: Reattach the axle, wheels, and lower the car back to the ground.
Handling Improvements
After upgrading to a limited-slip differential, drivers often notice significant improvements in handling characteristics:
- Increased Responsiveness: The AE86 becomes more responsive to steering inputs, allowing for quicker direction changes.
- Better Power Delivery: Power is more effectively transmitted to the ground, enhancing acceleration out of corners.
- Reduced Understeer: An LSD can help mitigate understeer, leading to a more balanced driving experience.
- Confidence in Performance: With improved traction and stability, drivers can push their limits with greater confidence.
Conclusion
Upgrading to a limited-slip differential is a worthwhile investment for any AE86 owner looking to enhance performance and handling. While the initial costs can be significant, the benefits in terms of traction, stability, and overall driving experience make it a popular modification among enthusiasts. Whether you’re a weekend racer or simply enjoy spirited driving, an LSD can transform your AE86 into a more capable and enjoyable machine.
