Um, first off, if you do the crime, do the time. The right thing to do is to pay the ticket, take the points, and deal with the insurance. Let it be a lesson to you.
Ok, now that my "righteous" side is out of the way, let me give you a tip (This will only work if you have a clean record, in most cases).
1. Find out who the prosecutor/city/county/state's attorney is who handles traffic violations.
2. Go visit the prosecutor in his/her office well before court date.
3. Explain to the prosecutor that:
a. You admit you were going fast.
b. You are sorry you did it and won't let it happen again.
c. Offer an explanation that you had just installed a new part, and picked an area out in the country to run up the speed a bit to see how it was working, solely because you didn't want to endanger anyone else.
d. Apologize again.
e. Ask if there's any way to drop this on the condition that you don't have any same/similar incidents in however long they like.
f. Bribe with sexual favors if you are pimp enough.
You might, just might, have a cool person take the ticket and say "get out of here", or make you sign an agreement, and let you off.
If they are not cooperative, then you are probably gonna get your azz handed to you.
Good luck, and quit doing triple digit speeds on public roads. It isn't a track out there, you know.
