Race-Focused M3 Countersink Washers from 3Racing

These 3Racing aluminium countersink washers are specified for applications where flush seating and repeatable fastener geometry matter. The anodized pink finish provides corrosion resistance while making inspection of mounting points quicker during setup changes and parc ferme checks.

Setup and Tuning Considerations

The countersink profile reduces protrusion and potential interference with bodywork or aerodynamic surfaces. For competitive builds, consistent washer thickness helps maintain suspension geometry and repeatable torque readings when tightening hardware.

Compatibility and Workshop Usage

Standard M3 dimensions allow easy integration into common chassis and bulkhead interfaces. Keep a set in the toolbox for quick swap-outs during service intervals and when refining fitment or weight distribution.

top stuff indeed very fast postage price $$$ so good as trust me sakura zero all pink all hop ups lol.....this site rocks i saved so much throught these guys you will also

Will using these washers affect torque calibration?

Yes, adding a countersink washer changes fastener stack height and can alter torque readings; account for the washer when setting torque to ensure consistent clamp force.

Are they suitable for repeat pit service?

The anodized surface resists wear from repeated removal and fitting, making them practical for parts that are serviced frequently during race events.

Do they assist with aerodynamic clearance?

By seating screw heads flush, these washers reduce surface interruptions that can disturb airflow on exposed panels, which is useful for finely tuned setups.
