Yes, if it's inline, you'll need the 5.5mm pinion.
Also, check and see how the motor shaft is in relation to the rear axle. If the motor shaft is lower than the axle, you'll need the white offset Slot.It gears. If they are lined up, then you can use the standard colored gears.
I mention this because my Flyslot Porsche 997 motor was lower than the rear axle. I'm guessing your Ferrari could be also...
