I use smaller higher kv motors for my speed cars. Lower kv and/or bigger motor is just way too much torque and no way able to control of the line. Sure you can gear it high enough to control the torque, but pay for it by adding more time in your E.T. I have spend a bunch of mula on different motors and different cars to come to that conclusion. I've blown up countless tires just at launch with the overdose of torque. Most blow tires during a run and not within the first few feet. You need to find the happy medium of power to weight ratio in your particular car. In my case it's around 200-300W per LBS.
You can use startup power, higher timing, current limiter to control torque, throttle curves, etc, but a smaller higher kv motor is a whole lot easier to deal with. Totally different setup compared to offroad racing.
As in if it's easier on an ESC, it can be up to a point.
