Important Note: Please be advised that the clutch kit does not include a disk alignment tool. It is imperative that you procure your own tool for this purpose. Proper alignment of the clutches is crucial before installing the gearbox. Any form of side stress applied to the clutch disk can lead to premature damage of the spline teeth and bending of the disk. It is essential to execute a flawless installation, ensuring no side loads from the gearbox are exerted on the disks.

Furthermore, understand that due to the specific nature of use associated with this clutch, OS Giken does not provide any warranty. This product is designed solely for motorsport applications, and any installation errors are your responsibility; no exceptions will be made in this regard. However, if your project does not go as planned, a serviceable kit is available at a reduced cost, offering a viable solution.

Performance Highlights:

• Unmatched Performance and Durability: Designed to provide exceptional performance while remaining suitable for daily driving.
• Torque Handling: Successfully fitted in vehicles with torque exceeding 350ft-lbs, capable of handling up to 450ft-lbs tq at the wheels.
• Smooth Operation: Despite an unsprung disk, this clutch ensures a smooth driving experience without jerking during take-off. As the unit heats up, it becomes even quieter and smoother, enhancing the overall driving experience.
• Alert to Caution: This clutch offers no forgiveness for shifting errors, which can result in broken flywheel bolts, thats why must be used with ARP Flywheel bolts.
• Break-in Period and Noise: Some noises may occur during the initial break-in period; however, OS Giken indicates that no specific break-in period is required, and the clutch can go straight to the racetrack. Expect noises during clutch engagement and take-off similar to those found in motorsport bikes and high-performance brakes on cold stops. These noises will diminish over time while functionality remains unaffected.
• Engagement Efficiency: Allows for engagement of the next gear with just 60% clutch pedal pressure, regardless of RPM when it bites, it does so with full force for maximum performance and power delivery.

Conclusion: This highly functional and robust clutch outperforms expectations, delivering unmatched performance while remaining suitable for daily driving. Consider its functionality and performance over any associated noises, as they diminish with time.

From OS Giken: The STR Clutch lineup is engineered to handle high-capacity power while retaining a relatively light clutch pedal. This technology was developed in response to racers' demands for a lighter clutch during long endurance races in Japan, as heavy clutch pedals lead to driver fatigue.

The STR2C Twin Plate features solid hub clutch disks for efficient power transfer, reliability, and strength under heavy use. The end result is a quiet, reliable clutch set that will last for years before needing an overhaul. The STR2C is rated for up to approximately 575 lbs-ft of torque maximum, making it ideal for pure motorsport use or dual-purpose vehicles.
