I have a brand new set of DP Motorsport Carrera Cup wheels in 5x120, one set in 18" and one set in 17." DP made a very limited production run of these wheels in BMW fitment in 1997. These wheels are VERY rare and very well made. They use Work wheel halves. They have been sitting in boxes, untouched, since '97.
17x8" et40 square setup for $1850 / set plus shipping or local pickup in Seattle.
18x8" et40 front & 18x9" et40 rear for $2900 plus shipping, or local pickup in Seattle.
