The Macht Schnell Competition Stud Conversion Kit is engineered for drivers who demand maximum strength, safety, and efficiency—whether on the track or the street. Designed to replace factory wheel bolts with a motorsport-proven stud-and-nut setup, this kit delivers faster wheel changes, improved safety, and a more professional race-ready solution.
All Macht Schnell Competition fasteners are hardened and tempered to DIN/ISO 898 strength class 10.9, meeting or exceeding statutory requirements worldwide, including the USA. Every single stud and nut undergoes individual testing, not random sampling, ensuring consistent quality and precise manufacturing tolerances.
Each fastener features a durable black zinc coating for OEM-like appearance, corrosion resistance, and long-term wear protection. For optimal safety in competitive use, studs and nuts are also available individually and are recommended to be replaced after every race season.
