Fire extinguishers are mandatory in all cars that will see the track and should be mandatory in all street cars. There's no worse feeling then watching your car burn to the ground without the ability to do anything about it. Unlike most fire extinguisher mounts available, all of Rennline's mounts install directly to the factory seats and do not compromise seat travel or leg room in anyway. Constructed from aircraft grade aluminum and meets all requirements for racing series or other organized track events. Designed to be used with most standard 2.5lb fire extinguishers, all hardware and installation instructions are included. Includes Fire Extinguisher and Mount.
