FCS II Mayhem Driver PC Carbon Quad Rear Fins | Turn Your Thruster Into a Speed Machine
Pull the centre fin, click in a set of rears and the whole board changes personality. These Driver quad rears carry Matt "Mayhem" Biolos' drive-focused DNA to the back of your board — more speed down the line, extra hold through turns, and that lively quad looseness when you get over the top of it. Matched to the White Driver tri set, they keep your five-fin board covered for every condition.
Key Technical Features
Matt "Mayhem" Biolos template: Designed with the Lost Surfboards mastermind whose boards and fins sit under the world's best power surfers.
Driver rear template: Scaled to pair with the Driver front fins — drive and hold off the bottom with the fast, skatey release only a quad setup gives you.
Performance Core Carbon (PCC): FCS's fastest-responding construction — a carbon tissue inlay delivers uniform base-to-tip flex and instant energy return.
Quad rear set: Two rear fins with 80/20 foils for speed, hold and clean water flow between the fins.
FCS II System: Keyless, tool-free install — click straight into your FCS II plugs and paddle out.
Why You'll Love It
For anyone with a five-fin board who wants two boards in one — thruster control one day, quad speed the next. The White rears come in Medium (65–80 kg) to match the White Driver tri set; if you ride Large, go the Blue colourway.

About FCS
FCS is the global benchmark in surfboard fin systems, born on the beaches of Australia and now ridden by the world's best surfers. Since inventing the removable fin, FCS has obsessed over the connection between board, fin and wave, engineering templates and materials that turn a surfer's intent into instant response. The FCS II system made keyless, tool-free fin changes the industry standard.
The MB signature range is shaped with legendary Lost shaper Matt 'Mayhem' Biolos, whose templates are ridden by elite team surfers in the most critical waves on earth. Built in Performance Core Carbon, these fins deliver the speed, drive and release that define high-performance surfing.
