12x1.5 BBS Wheel Stud is made in Germany for BMWs. Perfect for owners who spend a lot of time switching between street and track wheels. Superior strength compared to wheel bolts and they are easily installed. These studs come in standard 75mm overall length. For most BMWs, 20 is the minimum that you'll need, but it's a good idea to get 2 or 3 spares. Priced individually (per stud).
