I had these made before I sold my E46 M3, but didn't receive them until after the car was sold. These stands are made of unpolished steel, 5x120 bolt pattern, 12" in height from the base to the center opening of the hub. A cut-out of the M3 logo was also incorporated near the base of the stand. They can be polished or sandblasted/painted/powdercoated to give a nice finish.
Prefer local pickup in san mateo. Asking for $80each.
