The Honda S2000 is a beloved sports car known for its high-revving engine, lightweight chassis, and sharp handling. However, like any performance-oriented vehicle, there are always areas that can benefit from upgrades to further enhance its capabilities. One such area is the S2000 rear end. The rear suspension, differential, and axle components are integral to the vehicle’s overall performance, especially when it comes to handling, traction, and stability. Whether you’re looking to improve your car’s performance on the track or enhance its overall durability and handling on the street, understanding the components of the S2000 rear and potential upgrades can make a significant difference in your driving experience. In this article, we will dive deep into the rear-end components of the S2000, the benefits of upgrading these parts, and some common modifications enthusiasts often pursue.

The Key Components of the S2000 Rear End

The S2000 rear end consists of several critical components that all work together to ensure the vehicle delivers a thrilling driving experience. These parts can be broadly categorized into the rear suspension, the differential, the axles, and the rear subframe. Let’s explore these components and their role in the overall performance of the vehicle.

1. Rear Suspension System

The rear suspension system of the Honda S2000 features a double-wishbone design, which is known for its excellent balance between handling and comfort. The suspension plays a crucial role in keeping the rear tires in contact with the road, maximizing grip during cornering, braking, and acceleration. A well-designed rear suspension system helps maintain vehicle stability and allows for precise control during high-performance driving.

However, the stock suspension can benefit from upgrades, especially for those pushing their S2000 to the limit on the track. Upgrading to performance-oriented coilovers, adjustable dampers, or stiffer bushings can improve handling by reducing body roll, enhancing cornering ability, and improving responsiveness. Additionally, upgrading the rear sway bar can help fine-tune the vehicle’s balance, particularly if you want to dial in oversteer or understeer characteristics.

2. Differential

The differential in the S2000 rear end is responsible for transferring power from the engine to the wheels while allowing the wheels to rotate at different speeds during turns. The stock open differential in the S2000 is fine for most driving conditions, but it does have its limitations, especially when it comes to high-performance driving or racing. Under high-load conditions, the stock differential can cause one wheel to spin more than the other, which results in a loss of traction.

Upgrading to a limited-slip differential (LSD) is one of the most effective ways to improve rear-end performance. An LSD helps distribute power more evenly between the rear wheels, improving traction and stability, especially during hard cornering or on slippery surfaces. Popular options for S2000 owners include clutch-type LSDs and helical LSDs, both of which provide excellent traction and better control in high-performance scenarios.

3. Rear Axles and Driveshaft

The rear axles and driveshaft are responsible for transferring rotational force from the differential to the wheels. These components are crucial for handling the high torque produced by the engine and ensuring that power is efficiently transmitted to the ground. Over time, the stock axles may experience wear or be prone to failure, especially if the car is driven aggressively or used for motorsports.

Upgrading to stronger, reinforced axles and driveshafts is an excellent way to increase reliability and durability. Aftermarket options are available in various materials, such as chromoly steel or billet aluminum, which are designed to withstand higher levels of torque and provide greater longevity under extreme conditions.

4. Rear Subframe and Suspension Bushings

The rear subframe is the structural component that holds the rear suspension in place. Over time, the bushings that connect the subframe to the chassis can degrade, leading to increased play, noise, and reduced handling performance. Upgrading to solid or performance bushings can significantly improve the stiffness of the rear end, which translates into better handling and more precise control during high-speed maneuvers.

Additionally, upgrading the rear subframe to a stronger, more rigid design can help improve overall handling performance by reducing flex and increasing chassis rigidity. Some S2000 enthusiasts opt for subframe braces or reinforcement kits to further enhance the rigidity and structural integrity of the rear end.

Popular S2000 Rear-End Upgrades

Upgrading the S2000 rear end is a popular modification among enthusiasts looking to take their car’s performance to the next level. Below are some of the most common rear-end upgrades for the S2000:

1. Coilover Suspension Kits

A performance coilover suspension system allows for complete adjustability, enabling owners to fine-tune ride height, damping, and stiffness. Coilovers are especially beneficial for those looking to improve cornering performance and reduce body roll during aggressive driving. Popular brands like Tein, KW, and Ohlins offer coilover kits specifically designed for the S2000, providing a wide range of adjustability and performance benefits.

2. Limited-Slip Differential (LSD) Upgrade

As mentioned earlier, upgrading to a limited-slip differential is one of the most beneficial mods you can make to the S2000 rear end. By improving traction and power distribution between the rear wheels, an LSD will significantly enhance cornering stability and overall handling. This is especially noticeable when driving at the limit on the track or when driving aggressively on twisty roads.

3. Stronger Rear Axles and Driveshaft

For those who frequently push their S2000 to its limits, upgrading to stronger axles and driveshafts is an excellent choice. Brands like Driveshaft Shop offer aftermarket axles and driveshafts made from materials like chromoly steel, which can handle higher levels of stress and torque. These components are particularly important for those with heavily modified engines or who participate in motorsports.

4. Rear Subframe Reinforcement Kits

Subframe reinforcement kits are designed to reduce flex in the rear subframe, ensuring a more stable and rigid rear-end assembly. These kits typically include braces and additional support to increase the overall strength of the subframe. This upgrade is beneficial for enthusiasts who track their S2000 or want to improve the car’s structural integrity.

5. Upgraded Rear Sway Bars and Bushings

Upgrading the rear sway bar helps to control body roll, reduce understeer, and improve overall handling. Pairing a new sway bar with upgraded bushings can make a noticeable difference in how the car behaves during spirited driving. Stiffer, high-quality bushings help to eliminate play in the suspension and offer more precise handling response.

Conclusion: Enhancing Your S2000 Rear End for Performance and Reliability

In conclusion, the S2000 rear end is a critical area of the car that can significantly affect the vehicle’s handling, traction, and overall performance. Whether you’re looking to increase your car’s grip on the track, improve reliability during high-torque applications, or enhance the overall driving experience, upgrading the rear-end components is a worthwhile investment. From performance coilovers and LSDs to reinforced axles and subframes, there are a variety of options available to suit every S2000 owner’s needs. By carefully selecting the right components and upgrades for your driving style, you can ensure that your S2000 remains a responsive, reliable, and high-performing machine for years to come.
