I have a square setup of HRE 19x8.5 ET30 FF15 Liquid Silver still in the box never mounted. Didn't get a chance to mount them before I sold the F10. This is complete in the box with center caps and all. Local pickup only in the Bay area so pm me your contact info and we can arrange a meet at a public location. Price is $1600.
