E82 E88 123i rear brake discs D1670, ATE caliper fit, fast road or track day

EBC D1670 rear discs for E82 and E88 123i (2007-2011) - built for cars with ATE rear calipers, not Brembo, not M Sport, not post-facelift conversions.

• Stage 1 or fast road spec: thermic black coating resists UK weather, no surface rust before first track day
• G3000 grey iron: better thermal stability than standard rotors under repeated stops - matters on B-roads or circuit laps
• Zero runout, precision ground: no judder, no pad knock-in period, just clean pedal response from cold
• Fits only ATE calipers: if your car has Brembo rears (e.g. some 135i or M135i), these won’t work - check before ordering
• Not OEM replacement: they’re a performance upgrade - thicker friction ring, better heat dissipation, longer life than worn factory units
