2 weeks ago I was minding my own business doing 121mph* when I went to brake for a corner and BANG - my rear trailing arm declared independance - annexing part of the chassis with it. I hit a stationary object at over 75mph* - but both myself and my father walked out without injury

* Measured via the still working GPS logger
All I can say is it is a bloody good job I have a roll cage!!
