OS Giken Mazda RX8 13B-MSP TR Series Twin Plate Clutch

OS Giken is well-known for making some of the most robust and high-performance drivetrain components available, especially for rotary engines. This TR Series twin plate clutch is a prime example, specifically designed for the 2004-2011 Mazda RX-8. If you're pushing your RX-8 hard, whether it's for track days, autocross, or serious street performance, a stock clutch just won't cut it. This twin plate setup is engineered to handle significantly more power and torque than the factory unit, ensuring smooth engagement and reliable power transfer even under demanding conditions.

The TR Series features a twin-plate design, which means it uses two friction discs instead of one. This larger surface area allows the clutch to dissipate heat more effectively and handle higher torque loads without slipping. OS Giken uses their own proprietary friction materials, balancing a strong grip with a surprisingly manageable pedal feel for a clutch of this caliber. The clutch cover is forged for strength, and the entire assembly is balanced to minimize vibration at high RPMs, which is crucial for the high-revving nature of the 13B-MSP Renesis engine. This kit is designed as a direct replacement for the factory clutch, meaning it fits right into the existing transmission bellhousing, though some modifications might be necessary depending on your specific setup and power goals.

When installing a high-performance clutch like this, it's important to have the right supporting components. You'll want to ensure your flywheel is in good condition or consider replacing it if it shows signs of wear. OS Giken recommends using their own lightweight flywheel for optimal performance and balance with this clutch kit. Proper break-in is also essential for the longevity of the friction discs; follow the manufacturer's instructions carefully to ensure the plates mate correctly with the flywheel and pressure plates. This clutch is a serious upgrade for any RX-8 owner looking to maximize their car's performance potential.
