Key Features

The SPEC Stage 3+ Clutch Kit incorporates several innovative features designed to maximize performance and durability:

• High-quality carbon semi-metallic full-faced friction material provides excellent grip, high friction coefficient, and long-lasting wear characteristics, making it suitable for high-powered street and race applications.
• Sprung hub design (application dependent) with double sprung configuration and spring cover relieves for enhanced flexibility, reducing shock loads and improving overall drivability.
• Heat-treated components ensure strength and durability under extreme conditions, preventing warping and maintaining consistent performance over time.
• Heavy-duty pressure plate with reinforced diaphragm spring delivers high clamp load, supporting increased torque capacity while maintaining a manageable pedal feel.
• Precision manufacturing and quality control ensure a perfect fit and reliable operation, reducing the risk of chatter or slippage during aggressive driving.

Construction & Design

The SPEC Stage 3+ Clutch Kit features a meticulously engineered design that combines advanced materials with robust construction techniques. The full-faced friction disc utilizes a semi-metallic carbon composite, offering a high friction coefficient and excellent heat dissipation. The pressure plate is constructed from high-strength steel with a reinforced diaphragm spring, ensuring consistent clamp load and resistance to fatigue. All components are heat-treated and stress-relieved to withstand the rigors of high-performance driving, providing a long service life and reliable engagement.

Installation & Fitment

The SPEC Stage 3+ Clutch Kit is a bolt-on upgrade that directly replaces your factory clutch components.
