Bit of a random one really, my mate was on track in his ek civic last night and spun off at the end of his session. nothing bad but the car cut out and would not start, got towed back to the pits where one of my other mates hopped in and flicked this 'inertia switch' and it fired up straight away. Anyway do ep's or any other toyotas use them, as this is the first I've even heard of them last night lol
