    Just hit a slight curb with my wheels today so I’m looking to see if anyone wants to buy them before I decide to powdercoat and keep them.

  3. New Wheels; Lugs, Spaces

    I'm new to the world of wheels and tires. I ordered a set of AVID.1 AV-06 18x8.5 matte bronze wheels and some 235/40R18 tires based on research and recommendations. I didn't think of getting aftermarket lug nuts, and from what I can find they need to be M12 x 1.5 lugs stock. I also read that...
