Alright, I guess the next step is 24x 775pro 4WD with multiple batteries. Or I could make this actually viable and use brushless motors?

Just cause the wheels turn doesn't mean the robot will. The understeer on this would be atrocious! But the gearbox and differential look awesome.

Re: pic: actual car, but every actual car part is replaced with FRC stuff

Needs suspension.
And grippier tires.
And a better diff than open
And a stiffer frame to make the suspension work well
And a cockpit (or electronics and make it like roborace)
*list continues*

SAE/FIRST join forces and produce FFC (FIRST Formula Competition)?

Re: pic: actual car, but every actual car part is replaced with FRC stuff

Oh, this thing will have a pretty hearty torque steer on account of the axles being different lengths. That small of a drive shaft isn't exactly stiff. And of course the weight imbalance exists but that's been mentioned and could be offset by the other things you need yet.
