These are by far the highest quality wheel studs on the market today. Made from aerospace quality chrome molly steel, and heat treated for maximum strength. The threads are rolled for additional strength. The result is a no-compromise NASCAR quality competition wheel stud that is highly resistant to wear and damage. The extended bullet nose holds the lug nuts in place and guides them on with no chance of cross threading. Finished with a zinc phosphate and oil coating to prevent oxidation and provide consistent torque values and loading. Single ended press in design fits all 911/964/993 hubs. See application below for length. Stock L1 is 45mm & 50mm, depending on model. Sold as each, 20 required per car.
