Sounds unlucky! How did you crash to do it?
I have done the same fracture once, but I was to blame. We had a tripple jump at Batley and I tried to clear it, whereas I should have just done the double and hopped the 3rd... So, I launched the upramp and landed at speed backend down.
the car finished the meeting fine, and I was actually lucky to have not done more.
I have had plenty more high speed accidents since, the ones where you have a gutt feeling it'll be broke before its even come to a rest - but it has survived more than it hasn't!
