Default Tamiya TT-01 Gearing Question

Looking at the table below, what size pinion should I get?
I have a 55 and 58 tooth spur, running a tamiya sports tuned brushed motor and mainly drift wheels.

I can't find any good info on the internet.

Larger pinion/smaller spur gives more top end/less acceleration/higher motor temperatures.

The sport tuned motor can probably pull a ratio around 6:1 quite easily. Aside from that, just gear to suit your needs.

If drifting with the sport tuned you can go with a 24/58. Remember to run a heat sink and even a fan on the motor.
