Race-oriented M3 flat washers from 3RACING

For drivers refining setup or swapping parts between events, consistent hardware matters. These 3RACING purple aluminium M3 flat washers deliver uniform bearing under heads and nuts, supporting repeatable torque settings during setup changes.

Material and thickness considerations

Aluminium provides a balance of reduced mass and adequate surface strength for fastening duties. The 4.0mm thickness gives a predictable stack height and helps distribute clamping loads, which is useful when tuning suspension geometry or mounting electronics brackets.

Use cases in competitive builds

These M3 washers suit common mounting tasks in racing cars, from body mounts to servo and shock hardware. Keeping a stock of matching washers ensures consistent assembly and removes a variable when refining setup between heats.

How do these washers affect repeatable torque settings?

They standardise the bearing surface under the fastener, which helps achieve consistent torque readings and reduces variability when reassembling suspension or mounting points.

Should I use them under nut or head for best results?

Use them where the load needs spreading. For low-profile heads or thin panels placing the washer under the head prevents pull-through, while under nuts it increases contact area on the chassis or bracket.

Are these useful for fine tuning ride height or geometry?

While not a primary shim, consistent washer thickness contributes to predictable stack heights. Use dedicated shims for precise ride height adjustments, but washers help maintain repeatability of fastened assemblies.
