The Carerra guide is sometimes too thick or even too deep for some slots, so it needs to be sanded down to make it thinner and maybe some depth shaved or cut off it.
That way the guide will be deeper in the slot and may hold on more. if magnets are removed from all the cars that may level the playing field.
