ARP wheel studs are the racer's choice for high-horsepower and track use. Cold-forged from premium 8740 chromoly steel, heat-treated to a nominal 200,000 psi tensile strength, and cadmium-plated for corrosion resistance, they handle the acceleration shock loads and lateral forces that overwhelm ordinary OE studs. This extended press-in kit is M12 x 1.25 with a long 2.535" under-head length and 0.585" knurl - extra length for wheel spacers on Subaru WRX/STI and BRZ. Sold as a set of 5 (one wheel).
