Our adapters are precision CNC machined from a 6.25" diameter billet of 6061-T6 aluminum for precise tolerances and a perfect fit. Edges have been radiused to eliminate stress risers, and only the highest quality heavy duty M12x1.50 studs are pressed into the adapter for the ultimate strength. Short cadmium plated open ended lugnuts are included with the adapter pair to easily verify thread engagement, save weight, and prevent corrosion. We take extra care to design and machine the highest quality adapters possible. These are the best adapters you can buy.
