X-Clutch XKMZ24005-1C Stage 2 Single Cushioned Ceramic Clutch Kit

The X-Clutch XKMZ24005-1C is a Stage 2 Single Cushioned Ceramic Clutch Kit engineered for the Mazda RX-8 1.3L rotary engine. Designed for high-performance street use requiring elevated heat capacity, this kit delivers a meaningful upgrade over standard organic clutch systems while retaining a high degree of drivability.

The Stage 2 cushioned ceramic (1C) disc features a dampening layer between the two friction surfaces, working in conjunction with a sprung hub to absorb drivetrain shock and smooth engagement. This dual-damping design provides pedal modulation that ceramic-only discs typically lack, making it suitable for track-capable street vehicles or high-horsepower builds that demand ceramic heat capacity without sacrificing everyday usability.

The kit is paired with a high-performance pressure plate featuring an engineered pivot point and diaphragm design that delivers positive pedal feel alongside increased clamping force over stock.

Key Features:

• Stage 2 Cushioned Ceramic (1C) disc — sprung hub plus cushion dampening layer for improved pedal modulation
• High-performance pressure plate — engineered diaphragm and pivot design for positive feel and increased clamping force
• Higher heat capacity than single-plate organic clutch kits — ideal for performance street and occasional track use
• Input shaft diameter: 1 inch
• Recommended use: High-performance street applications requiring elevated heat capacity
• Designed and tested in-house by XClutch (also known as Xtreme Clutch) in South Australia
