JY-BD286
Ventilated Brake Disc
R90 homologated. Runout you can measure in tens.
Ventilated brake disc line for European and Asian passenger applications, G3000-grade gray iron with alloyed carbon control. CNC-finished with disc-thickness-variation runout held ≤ 0.03 mm — the spec that decides whether a customer comes back with a pedal-pulsation complaint.
E-marked per ECE R90 with batch codes laser-etched on the hat. Coated hub faces so the disc does not rust to the wheel hub before it reaches the car.
