At my track we have a speed trap.
Top speed of my car is 60kmh, with a roll out of 57mm, motor rpm then is aprox. 17500
M7H, not sure if your calculations are correct.
Roll out is the distance moved with 1 revolution of the motor
roll out = wheel circumference / fdr
Assuming you're using standard rubber tires with diameter of 59mm, circumference would be 59 x pi = 185mm
With a roll out of 57mm you would be running a fdr of 3.25
