Yes. Turning 21 on your court date will save your license. The suspension is controlled by your age on the date of conviction. Since you will be 21 on your court date then you will not be suspended. In either event, when you go to court, and they call your name, ask to speak to the prosecutor. Ask the prosecutor to reduce your speed to 59 in a 45 so the charge will not even go on your driving history.

I agree with Mr. Yeargan, this will be fine as long as you are 21 on the date of conviction. Asking the prosecutor to reduce the speed or to change the charge to a city ordinance or a basic rules violation will keep anything from going on your driving history.
Wait for court and when you are called, try and get the prosecutor to reduce the speed and pay the fine. Take money with you so you can resolve it then and there. Since you are now 21, no suspension issues.
