You have effectively no chance of "fighting" this: as you point out, it is your word against an officer's and in my experience, the courts always believe the sworn, trained, and "neutral" (no personal stake in the outcome) officer over a driver trying to avoid a ticket. And as you also admit in your question, you "overcorrected," which comports with common, everyday experience that a vehicle does not roll over unless the driver does something careless (or it is hit by another vehicle)--a judge can rely on his own experience driving to conclude that logically, you just have been careless.What you may be able to do, if you otherwise have a good driving record, is get the prosecutor to offer you a plea to some lesser offense (less points and/or a smaller fine)--prosecutors will often do this. You would meet with him/her the day of court, when you get there.
