FCS II Mayhem Driver Quad Rear Fin Set - Blue (L)

New name. New Look. Mayhem's new performance template.

Designed in collaboration with shaper and pro surfer Matt Biolos, the Mayhem Driver Quad-Rears are a refined high-performance template built to perform across a wide range of boards—from elite performance models to everyday versatile boards like the RNF and Puddle Jumper.

Featuring a new aesthetic and signature design, this fin combines power, stability, and responsiveness in one versatile high-performance template.

Performance Feel

The Mayhem Driver provides powerful hold and smooth responsiveness.

The wide base generates strong drive off the bottom, while the tapered tip and curved trailing edge allow the fin to release cleanly through turns. Its elongated Carver-style template ensures stability and control in hollow waves and point-break conditions, making it ideal for surfers who want flowing carves and aggressive power turns.

The result is a fin that feels stable, fast, and precise, suitable for both performance-focused sessions and versatile everyday surfing.

Fin Template: Carver

Built for power, drive, and drawn-out turns.

The Carver template features an elongated outline with a high degree of sweep, allowing the board to hold its line through powerful bottom turns and extended carves.

This design generates exceptional hold and control, making it ideal for surfers who like to lean hard into turns and draw long, committed lines across the wave face.

Ideal Conditions: Point Break

Performs particularly well in:

• Open-face waves
• Down-the-line point breaks
• Long, carving turns on clean walls

Board Compatibility

• Designed to fit the FCS II Fin System.
• Recommended for boards with deep concaves and moderate-to-extreme rocker

Performance Core

Performance Core Carbon + AirCore combines lightweight AirCore technology with carbon tissue reinforcement across both sides of the fin. This lighter, stiffer and more performance-focused construction maintains strength through the base and central spine while preserving controlled flex through the tapered tip. Designed to complement the Driver’s elongated template, it delivers strong drive and stability through powerful turns, with fast rebound and a highly responsive feel under load. Ideal for powerful surfers who demand greater speed, control and response from their fins.
