The GKTech Lug Nut Adapter Set for the Nissan 370Z (Z34) allows you to convert from the factory M12x1.25 thread pitch to the more common M12x1.5—perfect for running a wider variety of aftermarket lug nuts or swapping over wheels from another platform. This kit includes 20 hardened steel adapters, offering a safe, reliable solution for changing thread pitch without replacing your entire stud set.
