Well, there are two of each direction, and they are marked left and right. The DA wheels are the same way. I've always liked that about these wheels, Honda thought about it and did it right. Most other similar style wheels are all the same, so one side looks different from the other. The RSX wheels are the same way, but more subtle. And yeah, like Heu said, they are meant to "scoop" air, though I don't think it's functional, it just looks cool, like the CRX is going to rip out the pavement with it's 100hp.
