CSOhara Duracon Differential Mount Rings work like 2 stage action. Under low force, such as when experiencing 1G, the limited restraining force allows for smoother movement. However, under high-load conditions involving driving torque and lateral G-forces, this component steps in to prevent excessive motion by canceling the rubber mounts but engaging with the mount's outer perimeter. This deliberate design choice effectively manages stress without compromising performance, ultimately enhancing traction.

CSOhara Aluminium Differential Mount Rings give you another option. If you are looking for higher suppression power than that made by Duracon, although using the same suppression method, you can expect higher effects by changing the material. During low-force situations, such as when experiencing 1G, the limited restraining force allows for smoother movement. Under high-load conditions involving driving torque and lateral G-forces, this component steps in to prevent excessive motion by canceling the rubber mounts but engaging with the mount's outer perimeter.

CSOhara Reinforced Rear Hub for High-Load Situations is designed specifically to address cracking issues that may arise from heavy loads with the installation of wide, high-grip tires. To mitigate these concerns, it is advised to incorporate this upgraded hub during hub-bearing replacement procedures. This reinforced hub comes equipped with bullet-type hub bolts, offering ease of wheel installation as a standard feature. The bullet hub bolts are 15mm longer than the stock bolts.

The renewed CSOhara large capacity differential case has become the standard for the S2000 owners in Japan. This differential case accommodates a maximum oil volume of 2.3L, ensuring optimal functionality for your vehicle (Minimum required oil volume is 2.0 Litre.) This helps prevent rapid temperature increases, subsequently maintaining the ideal operational conditions for the LSD and final gear.

CSOhara OS Giken Super Lock LSD is based on the OS Giken Super Lock 2-Way LSD (Spec X) and specifically tuned to CSOhara specification. It is meticulously designed to offer a neutral effect that seamlessly integrates with your vehicle's rotating dynamics. The precise consideration of lock timing and cam angle ensures a smooth and consistent locking mechanism, distinguishing it from conventional LSDs.

CSOhara Carrosser Cusco LSD is the 1.5WAY LSD featuring a unique concept that prioritizes balanced performance without tipping the scales towards overpowering acceleration or inadequate deceleration. Unlike conventional disc spring type MZ or spring type RS systems, its design ensures a refined and steady initial performance, offering perceived effectiveness beyond the standard settings. By keeping the configuration conservative, we eliminate abrupt shifts in acceleration and deceleration behaviors, providing a smoother driving experience.

CSOhara Reinforced Stud Bolt for Side Bearing Cap improves installation force of the side bearing cap in the differential. By utilising specially designed stud bolts, customers can now elevate the tightening torque to a maximum of 80N/m, a significant jump from the stock value of 45N/m.

CSOhara WPC plus Tin Treated Final Gear is available in 3.9, 4.1, 4.3, or 4.44. This gear set has undergone advanced WPC treatment to enhance durability, coupled with the additional benefit of tin shot treatment for increased surface strength.

CSOhara Solid Pinion Distance Collar stabilises of Pinion Bearing Preload. It replaces the stock pinion crushable collar of the final gear to ensure rigidity and prevent pinion oscillations. It effectively combats poor tooth contact resulting from heat damage and loss of bearing preload torque under heavy loads.
