I looked forever and when they did show up they were gone soon after. I would just buy new as you never know the thickness of the rotors and pad life.
Contact Long at LTBMW. He should be able to hook you up.
If you will be purchasing ANY AT&T services online or in store could you mention that you were referred by me? My Employee Referral ID is eo4489. This would be a great help and it costs you nothing, thank you!
