When you are building your classic Porsche there are a lot of considerations to be made, and none are more important than what actually holds the wheels on. These are top quality OEM studs in a variety of lengths to suit your specific build. Studs are a wear item, and on a car that frequently sees track use they should be replaced at least every two years to avoid fatiguiging of the steel itself.
