Lol yeah my membership just timed out, box is open again. I posted some information but the 9.5+22 and 11+15 is very close to the custom sizes many vendors will cut wheels like avant gardes and forgestars for the z. Look up specs on the forgestar f14 thread, it will look damn near perfect and require no spacers. There may be room for a 5mm spacer up front at the very most, if you wanna max flush without tons of camber.
in short, they are build to be zero camber max width and the lightest forged JDM wheel on the market.
