The 3RACING 3RAC-WF305/PU Aluminium M3 Flat Washer 0.5mm in purple is a concise solution for racers and tuners who require repeatable spacing adjustments. These ten thin washers are useful when trimming tolerances and refining geometry for improved consistency.
Aluminium shims provide low mass and stable support, so you can make fine incremental changes without upsetting balance. The 0.5mm thickness is ideal for micro adjustments in suspension, steering linkages, and hub spacing where small differences alter handling.
Use these M3 flat washers as shims under fastener heads, between stacked components, or to even-out load distribution when tightening. They are practical for both race-day checks and detailed bench setup when optimising your chassis geometry.
