Fantom Racing .012 Brass Motor Spacers are a must have for serious motor tweakers. Shims are a must have when rebuilding any motor, to properly shim the rotor so that it "floats" within the magnetic field. These can also be used to shim your chassis to reduce unwanted end-play in the suspension arms. Package includes twelve shims.
