Wheel Stud Kit 5pk Subaru WRX/BRX & Scion F

The ARP Wheel Stud Kit 5pk for Subaru WRX, BRZ, and Scion FR-S exists to replace factory studs that may be undersized, damaged, or prone to stripping under the stress of high-performance driving and aftermarket wheel applications. Whether you're upgrading to forged wheels, increasing tire grip with sticky compounds, or subjecting your vehicle to track duty, OEM studs can become a weak link in your suspension geometry. This five-pack kit delivers the exact replacement count needed for one axle, making it an essential upgrade for any serious WRX or BRZ owner.

Each stud in this kit measures 12 mm x 1.25 thread pitch, stands 1.750 inches long, and features a 0.585-inch knurl diameter for secure engagement with the wheel hub. Manufactured from chromoly steel and finished with cadmium plating, these studs deliver superior tensile strength compared to factory mild steel alternatives while resisting corrosion in salt-heavy climates. The cadmium coating also reduces galling during installation and removal, protecting the threaded portion from damage during repeated wheel service. This material combination is standard in professional motorsports applications where reliability and repeatability are non-negotiable.

Mechanics and enthusiasts benefit from this kit when installing larger brake packages, transitioning to lighter wheels with different lug hole specifications, or simply refreshing suspension fasteners after years of seasonal changes. Installation requires removing the wheel and caliper to access the hub, then pressing out old studs and seating new ones flush with the knurl. Proper torque specification—typically 65–75 ft-lbs for WRX and BRZ applications—ensures even clamping load and prevents stress concentration. Compatible with all 5x100mm Subaru WRX and BRZ models as well as Scion FR-S platforms, this kit eliminates guesswork and guarantees OEM-spec fitment.
