Yes, the Core-Lite Quad Rear fins are designed to be compatible with both FCS1 and FCS2 box systems, making them a versatile choice for most standard setups.

Yes, these fins are categorized as Quad Rear/Side Bite, meaning they are perfectly suitable for use as side bites in a 2+1 longboard setup or as the rear fins in a quad configuration.

The flat foil provides a consistent and reliable feel, offering a predictable release and clean water flow. It is a standard choice for quad rears because it helps maintain speed and stability through turns.
