Will these fit my wheels with the stock stud pattern?

These are M12x1.5 open-end lugs with a 70MM body. The included adapter gives you flexibility across different wheel mounting styles, but verify your wheel's lug seat and stud pattern match before ordering.

Do I need to do anything to these before installing them?

No prep required. The gold anodized finish is ready to install straight out of the box. Just hand-clean them if they've been in storage and you're good to go.

Are these suitable for track use or just street driving?

Aluminum lugs work fine for street and light-duty track use. If you're running high-impact racing environments, check with your series or track for material restrictions — some require steel for safety reasons.
