Twist-55 and Schulze U-Force 75

[captain harlock]

I ran my car on wednesday at the track and one of my friends tried it and all I can see on his face is an expression of amazement and impress. However, he told me that the car has so much torque and I might need to increase the no. of teeth of the pinion gear to decrease the spinning of the wheels and increase the speed of my rig. He told me so after I told him that my motor and U-Force 75 were very hot. I dont know what help can you provide. The car became incredilbly powerful and fast with this setup, by the way. Faster than I want it to be, but the setup is getting pretty hot.
