Product Description

The SPEC SB533F-2 Stage 3+ Clutch Kit is a high-capacity performance clutch engineered for BMW vehicles equipped with the 3.0 L turbocharged engines (N54, N55, B58) across model years 2007 through 2020. The full-face carbon semi-metallic friction disc paired with a rigid hub design provides superior torque handling and engagement precision compared to stock clutches, making it well suited for high-power street builds, aggressive tuning, and track use. The increased clamp pressure and heat-resistant materials help maintain consistent performance under repeated load and spirited driving conditions.

This clutch kit is ideal for enthusiasts pushing beyond OEM torque limits - especially those running upgraded turbos, tuning modifications, or performance enhancements. While the kit includes the clutch disc, pressure plate, and alignment tool, it **does not include a flywheel**; SPEC performance flywheels are recommended to fully capitalize on the clutch's capabilities. Installation involves removing the transmission and should be performed by a qualified technician, and a proper break-in procedure will help ensure long-term durability and optimal engagement feel.
