For racers refining suspension and steering geometry, the 3Racing Aluminium M3 Flat Washer 2.5mm delivers a consistent, low profile shim option. The purple washers aid quick visual identification during pit setup and component swaps.
These flat washers are suited for fine stack adjustments where precise spacing impacts handling. They pair with standard M3 hardware and are commonly used on 1/10 scale touring and short course cars to tune roll center and clearance without altering parts.
Manufactured from aluminium, the washers offer stable thickness and resistance to compression compared with softer shims. Their finish aids part sorting and routine servicing between runs.
