Re: Fire extinguishers and FIA list numbers

Hi Steve
As I understand it you must comply with Motorsport UK regulation K3, the relevant system being 3.1.3 below - ie plumbed in discharging into the engine bay and the cockpit using 2,25 litres of AFFF or ZERO 2000 extinguishant. A good example is Lifeline 360 Firemarshal 2,25kg system.
We really want to see you out in Clubmans next year
Best wishes, Pete
