If you have a car that is difficult to drive the easiest thing to do is to turn down the voltage, when you do that it is quite likely that your lap times will go down. It is nice to have a variable power supply, it is even better if you can control each lane independently. Some controllers have a "choke" feature built in and that can be helpful up to a point. You can also put a voltage regulator in the circuit for each lane or just use diodes to drop the voltage.
Switching to a less powerful motor is another option. It is nice if you know the power ratings of the motors that you are considering, the Slot Car News Motor List is a great reference for data of that sort, but it may not be up to date. Be aware that RPM measurements do not always tell the whole story about how a motor will perform on the track.
Tuning the car to handle better is another possibility, although many people prefer to keep their cars stock or nearly so. The length of your track is not as big a factor as you might think, a car that handles well will do so on any length track. If the car is actually under powered you would feel that mostly on a track with long straights. Going to a more powerful motor might get you more top speed, but if the handling is not up to par your lap times could go up.
