The 78mm Endurance Race Stud Kit represents the pinnacle of fastener engineering for track-focused BMW M builds. Forged from a proprietary steel alloy and manufactured domestically by a nuclear-grade supplier, these studs deliver 260,000 lbs minimum axial tensile strength at 12.9 hardness—engineered for the demands of endurance racing. The bullet-nose design accelerates nut installation, while the expanded stud body diameter maximizes clamping force without compromising nut engagement smoothness. Black zinc coating provides corrosion resistance, and the extended thread design accommodates up to 20mm spacers. Available in double-nut or limited 5mm hex configurations.
