The Project Kics Leggdura Racing Shell Type Lug Nuts

Kics is proud to announce the release of an all new racing lug nut. It's called LEGGDURARACING. Derived from the Italian word "leggero" for light and "duralumin" for its material composition, the LEGGDURA RACING lug nuts are made in Japan from forged A7075-T6 Aluminum alloy. Weighing a mere 22 grams per lug nut, the 20 piece set (16+4 locks) is less than 0.25 pound per wheel corner compared to stock weight of 0.50 pound per corner. That’s a 50% total weight savings which can help increase the performance aspects of braking, cornering, and acceleration.

  1. The color won't hold up after some time.

    By The do the job, they just don't hold the color much. February 15, 2022

    I bought the black ones to match my wheels but after almost 3 years the caps to these lugs have lost their color. Some have turned a gold color while others have a green/blue/gold tint to them. I've uploaded a picture of one wheel. They're all like that too. Might just roll without the caps.

  2. Excellent Look and Quality with Frustrating Tools

    By SUBAZULsti February 16, 2017

    These delivered exactly the look I was going for with my new black Enkei Raijins. They are very high quality, but I wouldn't call them light. They weigh 40 grams each, which is 12 grams heavier than the stock lug nuts. However, the locking and regular lug nuts all weigh the same, so you get a nice balanced wheel. My only criticism is with the tools. None of them are cut to fit a 1/2" drive like they should be. You have to use a 19 or 20mm socket to hold the key socket. The regular lug nuts are 17mm and require a 20 mm socket to hold them in your wrench. I'm extremely satisfied otherwise.
