For drivers and tuners who demand repeatable results, the 3RACING Aluminium M3 Flat Washer 1.5mm in light blue provides consistent contact under fastener heads. These washers help standardise clamping points so adjustments return to the same baseline during setup changes.
Use these washers where precise clamping and repeatability matter, such as shock mounts, bulkheads and body posts. They help maintain consistent stack height and reduce variations introduced by differing screw torque.
As a low-mass, low-profile accessory, the 3RACING washer simplifies hardware swaps and makes it easier to tune chassis geometry without introducing uneven bearing points. Keep several packs on hand for quick race-day repairs.
