Will these fit my car's studs?

These are M12 x 1.25 thread pattern — the most common size across modern cars, trucks, and performance vehicles. If you're unsure of your stud size, measure an existing lug nut or check your vehicle's service manual.

Do the lug nuts need painting or prep before install?

No prep needed. The anodized green finish is factory-applied and ready to install straight out of the box. If you prefer a different color, they can be stripped and refinished, but that's optional.

What's the difference between the 35mm short and longer options?

The 35mm short body is designed for wheels with deeper center bores or offset designs where extra lug nut length could interfere with wheel fitment or cosmetics. If your wheel has plenty of clearance, either length works — it's a fitment preference, not a functional requirement.
