The Leggdura Racing 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. Absolutely Perfect

    By Demariners June 8, 2018

    Love these lugs. Actually everything by project kics are terrific. What I really like about these is the 2 part design. You can't scratch these if you install them correctly. They are well built and are stunning. I think anyone that has custom wheels should have these.

  2. Quality

    I am very pleased with the quality and finish of these, as well the added security of keeping my forged wheels in their place.
