About Project Kics: Japan's Standard for Wheel Hardware

Project Kics is the high-performance wheel accessories brand of KYO-EI, a Japanese manufacturer with over 50 years of experience crafting precision automotive hardware. Project Kics was built on a simple but uncompromising philosophy: even the smallest fasteners on your vehicle deserve the same engineering attention as any other performance component. That ethos has made the brand a go-to for JDM enthusiasts, time attack competitors, and daily drivers who refuse to cut corners on quality.

Headquartered in Chūō-ku, Osaka Prefecture, Japan, KYO-EI has been producing innovative automotive accessories since 1977. Under the Project Kics name, the company channels decades of motorsport experience into a focused lineup of wheel-centric products — all designed in Japan and manufactured to tolerances that meet or exceed OEM standards. The brand holds certifications from ISO, NAPAC, and JAB, providing independent verification of its rigorous quality controls.

Engineering That Earns Track Trust

What sets Project Kics apart is its commitment to material integrity alongside style. The brand employs forged 4130 chromoly, aerospace-grade Duralumin (A7075-T6), and titanium alloys depending on the application — delivering exceptional strength-to-weight ratios that matter in both racing and street use. Products have been trusted by professional teams competing in Super GT, D1GP, and Formula Drift Japan, which speaks directly to the durability demanded at the limit.

The brand's flagship wheel lug nuts span several iconic product lines — from the ultra-lightweight Leggdura Racing series to the sleek R40 Iconix and the compact Monolith T1 — giving builders options whether they prioritize weight savings, aesthetics, or security. For those who need to fine-tune their wheel fitment, Project Kics wheel spacers made from T6061 aluminum offer a reliable solution with universal bolt-pattern compatibility. The brand also produces wheel locks through systems like the R40 Heptagon lock that combine anti-theft protection with motorsport-grade security.

Beyond the nuts and bolts, Project Kics sweats the details that finish a build. Their tire valve stem caps, such as the Leggdura Racing caps crafted from Duralumin in Japan, carry the same material philosophy as the rest of the lineup — lightweight, durable, and visually cohesive with the rest of your wheel setup. The brand also offers wheel-related accessories including hub centric rings, ensuring proper centering for aftermarket fitments.

Built for Enthusiasts, Trusted by Professionals

Whether you are building a dedicated track car, refreshing a show build, or simply upgrading your daily driver with hardware that won't let you down, Project Kics delivers products that blend precision engineering with distinctly Japanese craftsmanship. Their broad thread-size coverage and anodized finish options — including black, neochrome, blue, red, and titanium colorways — mean there is a Project Kics solution for virtually any vehicle and aesthetic.
