ARP 2015+ Subaru WRX/STI and 13+ BRZ Extended 5 Wheel Stud Kit
This ARP wheel stud kit includes 12 extended-reach studs designed for 2015 and later Subaru WRX and STI models plus 2013 and newer BRZ Toyota 86 and Scion FR-S. The 5mm extension over OEM length allows fitment of aftermarket wheels with deeper pockets or larger hub-centric rings while delivering reliable clamping force. Ideal for performance driving where secure wheel mounting prevents failures under high loads.
