I don't know what you're looking for. There isn't some abusable method for beating these cases.
I supposed the best you can do if you decide not to plead guilty is ask to see some sort of report of calibration of the officer's radar gun, which they are supposed to get every so often I believe, and hope that it's old or something. However, in the few times I've been to traffic court, the judge embarassed the FUCK out of people who try to plead their case. I think you're better off just going in, pleading guilty, hope they give you a break for being honest, and think of your fine as a driving tax.
