Hello Charlie,
Having "magnatraction" certainly adds traction and helps keep the cars in the slot. That leads to greater speed with the need for increased skill level to avoid de-slots. Inevitably the de-slots at greater speed can result in car damage.

As in most sports, events are defined into class-groups where like compete against like and in slot-car racing the categories can include "with magnatraction".
