How can I ask for a payment plan for a speeding ticket? (NYC)?

[pete]

Hey.

As the court date for my speeding ticket draws near i realize i may be facing a hefty fine of up to 300+ dollars. Do i have to ask the judge right away for the payment plan option or would i have to talk to the clerk?

Also the ticket i was issued said i was doing 82 in a 50mph zone. When i drove back to the highway the speed limit reads 40mph, would it be bad to bring this up in court as well?
