Note the manufacturing date: old-school JDM goodness.

These are 18x9, 5x114.3, and 42mm offset: for those of you that don't speak metric, that's a 5x4 1/2" bolt circle and 6 5/8" backspace. Weight is exactly 21 pounds on my postage scale. Typical Enkei 72.6mm centerbore. They will fit a variety of cars, including RX-8, '05+ Mustang, some Nissans, Toyotas, and even NC Miata with the right mods. If you're car has a 67.1mm hub, I've got some trick alloy hub rings that I'll throw in the deal. The casting appears to have adequate thickness to be milled to a 45 offset if needed.
I bought these earlier this year for a different project and the offset didn't work out, so other than cleaning up this one wheel for test fitting they are unused and stored indoors since I've had them. I'm asking $400 for the set. Currently located at my shop in Orange, I could deliver them in my travels around the Southland or bring them to the August event. Post here, PM, or email me through the board with your interest.
