Project Kics WKIZ3U Leggdura Racing Lug Nuts Blue M12x1.25 - 20 Piece Set with Laser Logo

The Project Kics Leggdura Racing Lug Nuts combine lightweight performance with OEM-level strength through their advanced duralumin construction. Made in Japan from forged A7075-T6 aluminum alloy, these lug nuts are named after the Italian word "leggero" (light) and "duralumin" for their material composition, delivering exceptional performance benefits for enthusiasts and racers alike.

Key Features:

• 20-piece set includes 16 standard lug nuts and 4 locking lug nuts with special key
• M12x1.25 thread pitch with blue anodized finish
• Laser-etched "Kics Racing Lug" logo on lug nut face
• Weighs only 22 grams per lug nut for reduced rotating mass
• 17mm hex size for standard socket fitment
• Closed-end design for finished appearance and protection
• Forged A7075-T6 duralumin construction as tough as OEM steel

These lightweight lug nuts deliver approximately 50% weight savings compared to factory lug nuts, reducing unsprung weight by about 120 grams per wheel corner. This weight reduction helps improve braking response, cornering performance, and acceleration. The duralumin construction provides strength comparable to OEM steel lug nuts while maintaining aluminum-like weight characteristics. The closed-end design with vibrant anodized blue finish enhances wheel aesthetics while protecting wheel stud threads from debris and corrosion.

Important: These lug nuts feature a tapered base and are specifically designed for aftermarket wheels with tapered lug seats. They are not compatible with factory wheels that use ball-seat or mag-seat lug nuts.
