Specifications
Part Details:
Running a wheel spacer over 5mm, a wider wheel, or just wanting easier wheel changes at the track all call for a longer stud than the factory piece provides. This ARP extended wheel stud kit is roughly 3/4 inch longer than the OEM stud, sized specifically for the 2015 to 2021 Subaru WRX and STI and the 2013 and newer Subaru BRZ, machined from heat-treated 8740 chrome moly steel with a 200,000 psi tensile strength rating.
Cadmium plated for corrosion resistance and sold in a pack of five, enough for one wheel. Lug nuts are not included.

Frequently Asked Questions
Do I need extended studs for my spacers?
Any slip-on wheel spacer over 5mm generally requires an extended stud to maintain safe thread engagement. Check your specific spacer thickness before ordering.
Does this fit the older 2002-2014 WRX or 2004-2014 STI?
No. This kit is sized for the 2015 to 2021 WRX and STI. The earlier generation uses a different stud length and requires a different ARP kit.
How many packs do I need?
This kit is sold in packs of five, enough for one wheel. Order four packs for a full set.
Are lug nuts included?
No, lug nuts are sold separately.
