FCS II Mayhem Driver Quad Rear Fin Set

FCS II Mayhem Driver Quad Rear Fin Set

Developed with shaper and pro surfer Matt Biolos, the FCS II Mayhem Driver Quad Rear Fin Set is a refined, high-performance template made to work across a wide range of boards, from elite performance models to everyday shapes like the RNF and Puddle Jumper. As part of the Carver fin family, the elongated outline has a wide base, curved trailing edge and tapered tip, giving you the hold and control to draw out powerful, committed turns.

Built for surfers who like to carve and hack with precision, the Mayhem Driver excels in point breaks and hollow waves. The wide base generates strong drive off the bottom, while the tapered tip and curved trailing edge let the fin release cleanly through each turn. A high degree of sweep helps the board hold its line through aggressive bottom turns and extended carves, with smooth, flowing transitions between manoeuvres. A new aesthetic completes the signature design.

Performance Core Carbon + AirCore pairs lightweight AirCore technology with carbon tissue reinforcement on both sides of the fin. The result is a lighter, stiffer and more performance-focused build that keeps strength through the base and central spine while preserving controlled flex through the tip. It delivers strong drive and stability through powerful turns, with fast rebound and a responsive feel under load, ideal for powerful surfers who want more speed, control and response.
