The 3Racing Aluminium M3 Flat Washer set is intended as a precision shim kit for racers and tuners. These flat washers deliver uniform stack height and predictable clamping for setup repeatability during chassis tuning.
Each washer is produced to fit M3 fastening systems with a 3.5mm inner diameter, providing reliable alignment and helping to maintain consistent suspension geometry across runs.
Manufactured from aluminium with a blue anodised finish, the washers offer a balance of low mass and surface protection that suits competitive use where small weight and corrosion resistance matter.
Useful for shimming suspension, body mounts, or drivetrain brackets, these washers are a cost effective upgrade for tuners who need repeatable offsets without complex machining.
