The 3Racing Aluminium M3 Flat Washer set is a practical upgrade for racers and tuners who require consistent shim thickness and stable fastener seating. These washers support repeatable adjustments and help maintain correct stack heights in critical assemblies.
Manufactured from anodised aluminium, the M3 flat washers provide low mass, corrosion resistant support beneath M3 hardware. Their 4.0mm diameter works well where minimal added thickness and reliable load distribution are needed for precise handling adjustments.
Use these washers to fine tune suspension pickup points, correct servo linkages, or set body mount clearance. The red finish simplifies identifying tuning areas during pit checks and helps with quick visual verification of fitted spacers.
