Project Kics WKIC1P Leggdura Racing Forged Aluminum Lug Nuts Set Locks - 20-Piece

The Project Kics Leggdura Racing Lug Nuts are a premium, lightweight wheel fastener solution engineered for performance-minded drivers. The name Leggdura is derived from the Italian word leggero (light) and duralumin, reflecting both the design philosophy and the material: forged A7075-T6 aluminum alloy, manufactured in Japan to exacting standards.

At just 22 grams per lug nut, this 20-piece set reduces wheel corner weight to under 0.25 lb — compared to approximately 0.50 lb for a typical OEM steel lug nut set. That translates to a 50% reduction in unsprung rotating mass per corner, with measurable benefits to braking response, cornering agility, and acceleration.

The set includes 16 standard hex lug nuts and 4 heptagon security lock nuts with a matching key adapter. The closed-end, tapered-seat design is intended for use with aftermarket wheels. Available in seven anodized color finishes to complement virtually any wheel style.
