I regret to learn that. Are you aware if one or both discs are distorted?
I would refrain from replacing them without first verifying the callipers. If the callipers become stuck, the head may accumulate pressure, resulting in the warping of the disc.
I am uncertain about your precise model; nevertheless, in certain instances, AMG cars equipped with enhanced composite discs may also utilise conventional discs.
I cannot ascertain if yours is included, but another member or a brief search may provide confirmation. Best of luck organising it.
