These wheel studs are a great option for track and race applications, offering a stronger and more reliable setup while helping protect your wheel hubs from repeated installation and removal wear. Manufactured in the USA by a supplier for the nuclear power industry, they feature a 14x1.25 thread, black zinc finish, bullet nose tip, and an Allen key insert for easier installation. Built with 12.9 grade hardness and axial tensile strength up to 180,000 lbs, they also use a wider stud body diameter for increased strength while still maintaining smooth nut engagement. The extended thread design allows fitment with spacers up to 20mm, and each kit includes a complete set for all four wheels. Compatible with most BMW F and G chassis models.
