In this video I am trying to show you the part numbers that correspond to the discs required for the Brembo/ZZP performance brake upgrade. DBA has adjusted part numbers since a few years ago and no longer lists the Cadillac CTS-V brake code. Also some confusion with rear discs so hopefully this walk through helps you out. This advice in this video is general and my experience and may not be factually correct. Ensure you make your own enquires before purchasing. Thanks.
