Will these work with my factory wheels?

M12 x 1.5 is a standard automotive thread pitch. Confirm your current lug nut size before ordering — if your wheels came with M12 x 1.5 nuts, these will fit the same way.

Do I need a special key to remove the locking nuts?

Yes. The 4 locking nuts come with a matching key. Keep that key safe — you'll need it to remove those nuts later. Standard socket won't work on locking nuts without the key.

Can I paint these, or do they come finished?

They arrive finished in aluminum orange. If you want a different color, light abrasion and spray paint will work, but test on one nut first to ensure the finish bonds properly to bare aluminum.
