Do these fit my current wheels or do I need new ones?

The M12x1.25 thread matches most common aftermarket five-lug applications, but confirm your wheel's stud hole is drilled for that thread pitch before ordering. If you're upgrading wheels at the same time, these will work with any wheel that accepts M12x1.25 lugs.

Should I paint or coat these before installing?

The red anodized finish is sealed and ready to install as-is. Anodizing protects aluminum from oxidation, so no prep work is needed. They'll develop a patina over time depending on your climate, but that's normal.

What torque spec should I use when tightening?

Refer to your vehicle's service manual for the correct torque value — it varies by make and model. Overtightening aluminum lugs can strip threads, so use a torque wrench and don't exceed the manufacturer's recommendation.
