Some people use them some don't. In my opinion this is one of the best and easiest ways to tune your car. These can be quickly changed or removed to improve an ill-handling car. If the car pushes, try adding a stiffer rear bar and/or remove the front bar. If the car is loose, a stiffer front bar and/or remove the rear bar may be called for. My car has medium bars installed on the front and rear. In general the M03L is inherently more stable that the old M03, so you can run the car quite a bit stiffer in the rear (spring, shocks damping), without making the car loose.
