I´m with Bozak. Early 14" Miata alloys are around 12 lbs each. Though they are only 5.5" wide, you don´t need a wide footprint or precise feedback, right? And, given that this size isn´t "cool" anymore, they´re cheap enough to buy some extras in case you break one. I just bought a set of 16" wheels from a 2000 Miata; the bolt pattern, centrebore, lug nut bevels, and, yes, even offset, work just fine on my ´95 GT.
