Nice car, its a pity i would not be allowed at any race. ( not roar or efra event)
But the rear suspension looks realy nice.
About the Nosram esc , you can remove the fan , and cut heatink. but then you wont be able to use it with tc. If you use Parma speed 8 it would fit with the heatsink, this body is quite high, or can be cut lower whit only smal loose of front downforce.
