This optimization jig allows you to easily swap magnets, with or without an armature(must supply your own) with a rear axle slot and guide pin slot to use in conjunction with, whatever magnet downforce scale you use.
RC used this to match his magnets for his first magnet car nationals and made the main, first large scale magnet race in many years for him to participate in.
We always believe you should measure things as close as possible to how they will be used and this jig fits the bill perfectly
Comes with retaining clips as well, some minor trimming may need to be done depending on magnet tolerances to the clips
