One that sticks out in my mind. I was out in germany racing TC at the LRP masters, phil booth offered me a new A team chassis with cells slightly further forward etc for the mission, i built it all up and 29 heats later it was my heat again, one of my fellow team mates put the car down for me, only to be wiped out by an oncoming car, yup chassis broke

Another one was when the pred on road car was out (it was crap) and we were at wrexham, one car had spun on the straight, another swerved to miss it at full chat, he hit a kerb which made the car fly perfectly towards the fence, the car went through the wire fence taking all 4 wishbones off the car and the body looked as if it had been attacked with cheese wire
