Project Kics Hardware from JDMuscle

The best lug nuts for your Subaru are the ones that match your wheel's seat type and thread pitch exactly. For most Subaru owners running aftermarket wheels, Project KICS lug nuts in 12x1.25 thread are the go-to choice — lightweight, precisely machined, and built for tuner-style wheels. JDMuscle carries a full range of Project KICS hardware to finish your wheel setup safely and cleanly.

Project KICS is a Japanese brand best known for its Leggdura Racing lines. The Leggdura Racing Shell Type series uses a two-piece shell design with 35mm and 53mm lengths in closed-end and open-end looks, sold in sets of 16 plus 4 locking lugs. The R26 line is the classic street choice in 12x1.25, while Monolith caps add a finishing touch for M14 Monolith lug sets.

Popular picks include the Project KICS 12x1.25 Black R26 lug nuts and the Leggdura Racing Shell Type 35mm closed-end set. Always confirm thread pitch and seat type for your wheels before ordering — check your year and model, and measure the seat style if you're unsure. Pair them with wheels from our Fifteen52 lineup, browse all wheels and tires, or see more wheel accessories. Our guide on how to measure a car wheel size helps you get the specs right.

Frequently Asked Questions

Do Project KICS lug nuts fit my WRX or STI?

Most Subaru applications use 12x1.25 thread pitch, which the R26 and Leggdura Racing 12x1.25 sets cover. The critical check is your wheel's seat type — tuner wheels typically use a tapered 60-degree seat, which is what Project KICS lug nuts are made for.

What is the difference between open-end and closed-end lug nuts?

Closed-end lug nuts fully enclose the stud for a cleaner look and corrosion protection. Open-end lugs expose the stud tip and are preferred when running longer aftermarket studs for track use.

Do I need a tune after changing lug nuts?

No — lug nuts are hardware, not a performance part. Just torque them to your wheel manufacturer's spec in a star pattern and re-torque after 50–100 miles.

What is the Leggdura Racing Shell Type design?

It's Project KICS's two-piece design: a lug nut core with a removable outer shell in colors like red, blue, and black. The shells are replaceable, so you can refresh the look without buying a whole new set.
