New ones. The old ones are shinier, but the new ones are a much better style.
Fake bolt heads look stupid, just like the old fake spinner center caps on Chevrolets, or non-functional hood scoops on Mustangs. Form follows function, if it serves no function it shouldn't be there.
Are the bolt heads supposed to emulate a bead lock screw? If so, they are in the wrong place and should be located on the edge of the bead. Or are the bolt heads supposed to simulate a two piece wheel? Either way they look stupid.
