Will these work with my spacer setup?

These 60mm nuts are designed for extended stud clearance. If your spacers or wheel offset pushes the wheel face flush or recessed into the hub, the extra height prevents the nut from bottoming out on the stud before seating properly.

Do I need a special socket to install them?

Standard lug nut sockets work fine — the extended height doesn't change the hex size. Use the same tools and torque specs as your vehicle's service manual calls for.

Will the orange finish fade or chip off?

Anodized finishes are hard-coat treatments that bond to the aluminum. They resist UV fade and minor impacts better than paint. Heavy abrasion or curb rash will show bare metal, but normal wheel maintenance won't damage the coating.
