I called them and confirmed, 506 is the number stamped on the caliper carrier from the E46 325,328 or Z4. I ordered their bracket and hopefully it will get here sometime this week, I'm going to go pick up a couple of the carriers from the junkyard and I've got some nice fresh new Brembo slotted rotors. Hopefully I'll have it all installed by weeks end and I'll post the results. |
