In fact, if you look at most of the other OEM wheels (for a Japanese brand car at least), the wheels are cast aluminum made by Enkei.

It'll be hard trying to find an aftermarket wheel that weighs less than the sport package wheels. But then again, the weight difference should be negligible since the wheel width, contact patch, and tire width are going to be increased, or else, why bother with new wheels right?
