At the end of the day it is only metal and plastic, which can all be replaced.
It's one thing I've learnt though front doing a few track days, having a few offs and basically writing one car off. If you bring a car on a track, sh!t can go t!ts end up very easily. You have to be able to accept that you could lose your car in a big off. One wrong snap at pace and you can easily veer off into a barrier etc, even with a good run off. On grass you won't stop in a hurry...
