These 3RACING M3 flat washers are manufactured as thin 0.5mm spacers with an aluminium base and a titanium finish, offering a lightweight solution for fine mechanical adjustments. They are intended for precision shimming where controlled clearance and repeatability are required.
Use the 0.5mm washers to adjust bearing preloads, trim servo horn endplay, or fine tune suspension geometry. Their consistent thickness helps maintain setup repeatability across rebuilds and track sessions.
The titanium finish improves surface wear characteristics and corrosion resistance while keeping mass low, which is critical in high frequency vibration environments and when minimising overall vehicle weight.
