Extended Wheel Studs

The best extended wheel studs in this collection are the ARP kits built for specific cars — a 1.75-inch wheel stud kit for the 2002-2025 WRX and 2004-2021 WRX STI, extended stud 5-packs for the 2002-2026 WRX and 2004-2021 STI, and dedicated kits for the 2001-2005 Lexus IS300, 2003-2006 Mitsubishi Evo 8 and Evo 9, and Mazda Miata — plus forged BLOX Racing studs in universal 12 x 1.5mm sets of 16 and 20. Check your year, model, and thread pitch before ordering.

Wheel studs are the threaded posts your lug nuts clamp the wheel against. Extended studs add length for wheels run with spacers or thicker hubs, and replace factory studs that are stretched or snapped. Shoppers confirm application and length first, then choose a vehicle-specific kit or a universal set, browsing the wider wheel accessories range for matching lug hardware.

ARP supplies most of this collection and is known for fastener-grade hardware — exactly what a wheel stud is. Its Subaru range covers the 1.75-inch wheel stud kit for the WRX and STI and extended studs in 5-packs. Beyond Subaru, ARP lists studs for the 2001-2005 Lexus IS300, the 2003-2006 Evo 8 and Evo 9, and front and rear Miata kits split by generation.

BLOX Racing takes the universal route with forged extended wheel studs in 12 x 1.5mm, sold as a set of 20 or a set of 16. BLOX is a broad sport-compact hardware brand, and these sets suit cars whose thread pitch matches. The trade-off is fitment work: confirming pitch, length, and knurl fit against your hub is on you.

Project Kics is the companion name in wheel hardware, known here for lug nuts rather than studs. Extended studs usually pair with open-ended lug nuts, and Project Kics is a brand shoppers compare for that half of the job. Our roundup of our top 5 aftermarket wheels covers the wheels these studs are typically bought alongside.

Why would I need extended wheel studs?

Extended studs give extra thread length with wheel spacers or thicker mounting faces, restoring proper lug nut engagement, and replace damaged originals. Match the listed length to your car.

How do I choose between the ARP kits and the BLOX universal sets?

Choose ARP when a kit is listed for your exact car — WRX, STI, IS300, Evo 8 and 9, or Miata here. Choose BLOX when your car uses 12 x 1.5mm studs and no specific kit is listed, and verify pitch and fit first.

Are wheel studs hard to install?

Studs press into the hub, so installation means removing the wheel and brake hardware and pressing the old studs out and new ones in. It is doable at home with the right tools, but many owners have a shop press them.

How many studs do I need?

Count your car's studs per wheel and multiply by four. The BLOX sets of 16 and 20 cover four- and five-lug cars respectively, while the ARP 5-packs suit replacing one wheel's worth or keeping spares.
