For track-focused tuning, consistent hardware spacing is essential. The 3RACING 3RAC-WF315/BU M3 flat washers deliver repeatable 1.5mm offsets, supplied in packs of 10 to support setup iterations and component swaps during race prep.
Aluminium flat washers provide predictable, low-mass spacing that preserves fastener engagement and spreads load across mounting surfaces. They are suited to fine adjustments where small increments change handling or clearance.
Use these M3 washers for shimming suspension links, adjusting body mounts, or trimming small alignment issues between runs. Keep track of stacked washer counts so screw length and thread engagement remain within safe limits.
