Project Kics R40 Lug Nut

The Project Kics R40 lug nut is an open-ended, two-piece racing lug nut (also called a wheel nut or wheel lug) made in Japan. It is forged from lightweight SCM435 chromoly alloy. It is built for street and track drivers who want a secure, repeatable wheel fastening that also protects the wheel finish.

Key Features:

• Floating seat design: Each nut has a top section that spins freely on a tapered centering ring. This helps hold the wheel tightly and consistently, and it reduces the chance of scratching or gouging the wheel seat.
• SCM435 forged alloy: The chromoly steel is light and strong. It reduces unsprung weight without giving up durability.
• Open-ended racing design: The open end works with extended studs as well as standard studs.
• Tapered seat: The seat is made for aftermarket wheels with tapered lug seats. It is not intended for factory wheels that use a short-shank style nut.
• Patented construction: The two-piece design is the Project Kics R40 signature.

The R40 line is a good choice for enthusiasts who want a lightweight, precise wheel lug nut upgrade that holds up to spirited driving and track days.
