Guys I have been running the shit out of my car and loving it. The tires suck and get no traction (jaco tires), but it's still fun.

I have the mamba max pro in it with a 5700kv motor. The gearing is 110spur and 38 pinion. My esc was 135 temp, the motor was 190. I know I need to change up the gearing. Any suggestions? I don't race, just fly around the parking lot doing my own thing. Also looking for a little more top end.
