Harden Creek Slot Cars has developed new level 4 magnets for the venerable Life Like “M” car. The chassis as originally manufactured came with ceramic magnets. These were fine when running on a Life Like track that has thick, tall rails. However, today most guys run on Tomy or a custom tracks where the rails have less downforce. With the new level 4 magnets and good rear tires, the cars can now be run a full voltage with less de-slots. Changing the magnets is really simple.
