Just finished these, very rare OEM BBS RT222 and RT223 faces from the Z4 fully converted to 19" 3 piece forged step lip. A lot of machine work went into making these work with a full true 3 piece set up.
Current specs are:
19x9.5" et19 - 5x120 - 72.56cb
19x11" et23 - 5x120 - 72.56cb
Wheels currently have raw aluminum centers with polished lips and chrome hardware.
I am offering them at $3200 with the centers powdercoated any color you want, or fully polished. $3600 with brushed or polished centers with your choice of candy clear, tint or color. You will have your choice of red/gold BBS caps, black/chrome BBS caps or black BMW roundels.
