If your car is scrubbing speed in corners and you need to put huge amounts of power back into it to keep going, would loosening the car and reducing steering angle help a bit? It just seems that as my local tracks traction has come up my car seems less and less efficient in the bends, on the power a lot more, using another 1000+ milli-amp hours from my battery, and recording the hottest motor temps I have seen from my 1s.
