Project Kics Muteki Lug Nuts are a must for any high end wheels. Why updgrade your wheels and leave your lugs rusted and stock? * Compact Size 20mm x 34mm Compact size and shape (20mm diameter x 34mm height) to fit most tuner wheels with small lug holes. * Lightweight 36g Each nut weight 36g, smaller size than typical nuts at 60g, at each wheel helps improve car driving function. * Cold-Forged 1008 Steel Made by cold-forged 1008 steel which enables the nut to be made smaller and lighter, but strength to match or exceed other standard nut specs.
