TB03 can also do that, but with an internal gear ratio of 2.48:1, it's a lot harder to get below 4:1 final ratio without exploding your motor.
At the TCS Finals, we can use any spur/pinion gear combination we wish and I believe the top runners were running 64 pitch gears in their TB03s, geared in the low to mid 3's with 17.5T motors. I was geared at 3.894 with a 13.5T lol.
The thing with shaft cars is that throttle feels very direct and could have more acceleration off corners. That, along with a drivetrain that is very free, will allow you to carry even more gearing.
But what do I know, I don't even have a TB03R
