Will these work on my wheels without modification?

These fit any wheel with M12 x 1.25 lug holes. If your vehicle uses a different metric size or SAE thread pitch, these won't work — verify your thread spec against your OEM lugs or wheel documentation before ordering.

Do I need to prep or paint these before installation?

Aluminum naturally oxidizes but won't rust. Install straight out of the box. If you want a polished or anodized finish, that's a separate job — these ship ready to bolt on as-is.

What torque spec should I use when installing?

Refer to your vehicle's service manual for the correct torque value — it varies by vehicle and wheel type. Never guess on lug nut torque; over-tightening can strip threads or warp rotors.
