Upgrade the clutch system in your compatible Mini Cooper or Mini Cooper S with the OS Giken STR Series Dampened Single-Plate Clutch with Soft Diaphragm. Designed for Mini Cooper S R50 and R53 applications, this automotive clutch assembly combines responsive engagement with a diaphragm design intended to provide manageable pedal effort for street and performance-oriented driving.
The dampened single-plate configuration helps absorb drivetrain vibration and torsional shock, supporting smoother power transfer through the transmission. The soft diaphragm is engineered to deliver consistent clamp action while maintaining a more comfortable pedal feel than many aggressive competition-style clutch systems. This makes the OS Giken Part Number osgMN021-AJ6 a practical choice for drivers seeking dependable clutch performance without sacrificing everyday drivability.
OS Giken is recognized for precision-engineered clutch technology and motorsport-informed design. This STR Series assembly is built for direct vehicle-specific application and is intended for the listed Mini Cooper platforms. Verify vehicle details and existing drivetrain components before installation to ensure proper compatibility. Professional installation is recommended, including inspection of the flywheel, release mechanism, hydraulics, and related clutch components.
Application coverage includes Mini Cooper and Mini Cooper S models from 2002 through 2006, including the R50 and R53 chassis where applicable. Whether replacing a worn original clutch or refreshing a performance street setup, this OS Giken clutch provides a balanced combination of controlled engagement, reduced drivetrain harshness, and reliable power transfer.
