Over 100mph you'll lose your license automatically if you're found guilty, I think? That was my understanding.
Have you got a lawyer? I think the chances of not being found guilty are all but zero unless you've a lawyer to challenge things extensively; how recent the camera/device was calibrated and things. I'm going on half remembered stuff from when I used to work with a couple car-modding fanatics who were always getting caught at daft speeds.
Have to say though, if you were sitting at over 100mph, you probably deserve to lose it.
