Yokomo RP-109A Racing Performer Motor spacer set for M4/M3 series  [RP-109A]

A set of spacers that can be placed before and after the rotor of Racing Performer M4/M3 series motors.
In the conventional product (RP-091), the material of the shim (small), which wore out quickly depending on usage conditions, was changed from brass to stainless steel.
If this spacer wears out, it can lead to problems such as sensor damage, so please use it during maintenance.
