Planning to run spacers, different wheels, or just need to replace old, rusty studs? These PROJECT INNOVATION extended wheel studs are a high-quality upgrade. They're much longer than stock – the total length is 63mm, with a threaded section of 50mm. That extra length gives you plenty of thread engagement for safety, especially when using wheel spacers. They have an M12x1.25 thread pitch (super common for Japanese performance cars) and a knurl diameter of about 14.22mm to press securely into your hubs. They're made from strong Grade 10.9 steel and come in a cool gold finish. This 10-piece set fits a massive list of cars, including the Infiniti G37 (2008-2020), Nissan 370Z, Altima, Frontier, GT-R (check front/rear specifics), Subaru WRX/STI, BRZ, and many more Infiniti and Nissan models. Always double-check fitment for your exact year and model, but this is a go-to set for a ton of popular tuner cars.
