Spec Clutch SC543F Stage 3+ Clutch Kit - Full-Face Carbon Semi-Metallic

The Spec Clutch SC543F Stage 3 PLUS is the flagship performance clutch kit engineered for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can provide. Designed for drivers who need extreme holding power without sacrificing daily drivability, the Stage 3+ delivers a more manageable and friendly engagement than a traditional puck-style clutch while still dominating high-demand performance applications.

At the heart of the Stage 3+ is a full-faced carbon semi-metallic friction disc — a key differentiator from the Stage 3's puck-style design. This full-face configuration delivers superior drivability, exceptional wear life, and a higher friction coefficient, making it equally at home on a daily commute or at the track. The hub is double-sprung with spring cover reliefs for added flexibility, and all hub components are heat-treated for long-term strength and durability.

• High-clamp performance pressure plate

• Alignment tool kit
