I've decided on 15 inch rims, but now I cannot choose between the 18lb Enkei RS5s and the 12lb Rota Subzeros. I'm getting Falken ZE-512s if that information is needed. I'm guessing there will be performance differences because of the weight difference, but is Enkei stronger or better made than the Rota? My stand-point is that the RS5s look better but will perform worse than the Subzeros.
