Key Features

The ACT 4 Pad Sprung Race Disc incorporates several advanced features to optimize performance and durability:

• Constructed with high-quality ceramic friction materials that provide excellent heat resistance and consistent engagement during intense driving sessions.
• Four-pad design ensures even pressure distribution across the clutch surface, improving grip and reducing uneven wear.
• Heat-treated spring steel drive plate enhances strength and longevity, supporting repeated high-stress use.
• Heavy-duty torsional dampening springs are engineered with optimal spring rates to absorb torsional vibrations, reducing stress on drivetrain components and providing a more controlled engagement.
• Spring-centered design promotes faster, more precise shifts, making it suitable for racing and aggressive street driving.
• Compatible with smaller disc sizes, making it an excellent choice for lightweight, high-performance applications.

Construction & Design

This race disc features a heat-treated spring steel drive plate that ensures durability and resistance to warping under high temperatures. The ceramic friction material is selected for its superior heat dissipation and fade resistance, maintaining consistent performance even during extended high-RPM sessions. The four-pad configuration is precisely engineered to deliver balanced engagement and maximum grip, while the sprung hub design helps dampen torsional vibrations, resulting in smoother operation and reduced drivetrain stress.
