RaceQuip FIA Certified Composite Racing Seats provide the support to hold you firmly in place for increased car control. This seat is certified to FIA 8855-1999 specifications with FIA hologram affixed. The design is suitable for professional racing with its increased thigh and hip support along with extended shoulder and rib bolsters for extra containment. The shell is a one-piece lightweight, FRP hand-laid composite structure built for strength and durability. The design accommodates all Head and Neck restraints and there are five seat belt guides to handle 4, 5 or 6-point harness sets. The seat bottom and back cushions incorporate energy absorbing memory foam for comfort and safety. The seat material is a black mesh fabric for increased breathability with a more durable smooth covering in high-wear areas. The exposed areas of the shell are a shiny black gelcoat for a great look and easier cleaning. There are four built-in 8mm side mount threaded fasteners (brackets not included). Optional RaceQuip brackets allow the seat mounting to go from 0° Upright position to 30° Layback position. Seats weigh about 18lbs and are available in 15" Medium; 16" Large and 17" X-Large sizes.
