mate fight it, i recently got off a reckless driving charge..they had no solid evidence either. you could easily say it was an accident your not used to driivgn a car like this and you accidnelty gave it to many revs and lost a bit of control.

the penalty for reckless is min 6 months loss of licence and up 9 months. and a 1000 dollar fine. It goes on your record as a conviction too.

In your case though id say uv got a very good chance and you should def fight it. i used a lawyer, wasnt cheap but his damn good and well worth it.
