PIII-Approved Extended Wheel Studs M12×1.5 (+20 mm) – Toyota GR (1 pc)
PIII-Approved Extended Wheel Studs M12×1.5 (+20 mm) – Toyota GR (1 pc) When installing wheel spacers or aftermarket wheels with thicker mounting pads, maintaining adequate thread engagement is essential for safety. Extended wheel studs provide the additional thread length required to ensure the wheel is securely clamped to the hub under all driving conditions. The PIII Extended Wheel Studs are manufactured from high-strength Grade 10.9 steel, offering the strength and durability required for demanding fast road and motorsport applications. Compared to the original studs, they provide an additional 20 mm of threaded length, allowing the safe installation of wheel spacers while maintaining proper thread engagement. Manufactured with precise tolerances, each stud features a 14.30 mm spline diameter for a secure interference fit within compatible hubs, preventing movement under high loads. Their precision-machined threads ensure smooth installation and consistent torque application. Designed and manufactured to the highest European engineering and quality standards, these wheel studs deliver the reliability and confidence expected from a motorsport-grade fastening solution.

Only mechanically trained personnel should perform this installation. Total time required 2.5-4 hours. Important These wheel studs are intended as replacement or upgraded press-fit wheel studs for compatible hubs. Always verify spline diameter, stud length, and hub compatibility before installation. Wheel studs should be installed using the correct workshop procedures and torque specifications. After installation, recheck wheel nut torque after the first 50–100 km of driving.
