Anything that affects the emissions system definitely needs to be tested and certified in CARB-similar states, and some states have restrictions on some modifications that change, for instance, ride height, lighting, tires, etc. I can't imagine that hubcaps would fall under any such restrictions. That said, I fully agree with Darrell that you talk to SEMA. Not only could they give you guidance on regulations, but they can assist members with product marketing.
