Racing Performer M4/M3 motor spacer set
Coming from Yokomo and made for the Racing Performer M4 and M3 brushless motors is a new motor spacer set. It includes new stainless steel spacers that will wear less over time, especially when used in modified motors, where the previous set could lead to increased ball bearing wear and thus quicker wear. The set includes three spacers and it is available from now on.
