The 3RACING 3RAC-WF310/BU aluminium M3 flat washers are engineered as consistent 1.0mm shims for competitive tuning. Use them to fine tune clearances, preload settings and component seating where repeatability matters.
These flat washers offer predictable thickness and flatness for aligning suspension parts, motor mounts and gearboxes. Their thin, stable profile reduces variance between assemblies and helps maintain reliable handling behaviour when dialling in setups for different surfaces.
Machined from aluminium and anodized blue, these washers balance corrosion resistance with minimal mass. They are a practical part for racers looking to control weight distribution while preserving accurate fastener clamping across multiple rebuilds.
