Do these lug nuts work with my existing wheels?

These fit M12x1.5 studs directly. The included adapter expands compatibility — test-fit the adapter on your wheel seat before installation to confirm a solid seating surface.

Will these need any finishing work before I install them?

No prep needed. The gold anodized finish is ready to install straight out of the box. Wipe clean with a dry cloth before mounting.

What torque spec should I use when installing these?

Refer to your vehicle's service manual for the correct torque specification — it varies by vehicle platform and stud design. Hand-tight plus a quarter turn is not acceptable; use a torque wrench.
