The 3RACING 3RAC-WF310/5/PK aluminium M3 flat washer set is intended for precise stack height control and repeatable assembly during race setup. These flat washers maintain consistent thickness under common torque ranges and help preserve suspension and steering geometry.
Use these washers where minimal mass and consistent shim thickness are required to fine tune handling characteristics. Their uniform thickness assists in small incremental changes to geometry without altering overall stiffness significantly.
