A better ESC will help with allowing you to drive smoothly, as you can feed the power in with much more control than with a cheaper ESC.
On the motor front, i also dabble with scalextric and a common trick for the top guys there is to buy a box of motors (dozen or so) then run them all in (in water, 3v supply, two hours, ramping up speed, and so on) then put them on a basic dyno to check them out. Then discard (or sell on) the worst 80% of the motors and use the rest for racing.......... the same thing applies to silver cans in RC, the difference between a new, well run in, well looked after, *top end of tolerance* motor and one you just pull out of the box and run could be 5% or more.
