- Wheel Base (want it wider than track length)
- Track Length
- Wheel Tread Composition
- Drive Train Frame Rigidity (want it STIFF)
- Center of Mass (want it LOW)

Well, I wouldn't say WORTHLESS. There are times when you don't want to turn and that might be a feature.
But it is important to remember that your gearboxes/motors are merely part of your drive system. It is comprised of several parts (incomplete list):
- Main Breaker
- Motor Breakers
- Battery
- Motors
- Gearboxes
- Wheels
- Drive Surface
- Frame
- Controller
Each of these systems plays a HUGE role in the overall effectiveness of the system. While the gearbox and wheels may be big parts of it please make sure you analyze the whole system instead of simply saying "we wanna go fast".
Ricky Bobby didn't design his car, he just drove it.
