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 press-in kit is M12 x 1.25 with a 1.950" under-head length and 0.585" knurl, fitting Subaru WRX, BRZ and Scion FR-S hubs - a touch longer for a more secure stack with thin spacers. Sold as a set of 5 (one wheel).
