3RACING 3RAC-WF340/BK Black Aluminium M3 Flat Washer Set 4.0mm  [3RAC-WF340/BK]

Technical Flat Washers for Racing Builds

For competitive builders, the 3RACING Aluminium M3 Flat Washer 4.0mm in black provides a reliable way to control clamping forces and maintain repeatable geometry. These washers help stabilise joints without adding appreciable mass, which is important when tuning handling balance.

Material and Design Notes

Machined aluminium offers a favourable stiffness to weight ratio and natural corrosion resistance compared with untreated steel. The M3 sizing ensures predictable clearance and compatibility with common racing hardware while the 4.0mm thickness gives consistent preloaded spacing.

Applications in Setup and Tuning

Use these washers in suspension link adjustments, steering assembly shims, and body mount fine tuning where small changes to stack height affect handling. They are straightforward upgrade parts for maintaining symmetry and repeatable measurements between runs.
