Replying to Speeding Ticket -- Legit question

Background  (New York)- Met a cop doing 80 in a 55 I saw him hit his brakes so I just pulled over I had to really slam on the brakes so I didn't drive into the upcoming 30 (which I had no intention of slowing for) So when I came to a stop I was on the 55 side of the 30 sign

Question- When I get to court should I lie and say I was doing 80 in a 30 and argue that he wrote the ticket wrong? or would they just give me a ticket for 80 in a 30.
