This Brembo Prime Line front brake disc uses Dual Cast construction: a ventilated cast iron braking ring with an aluminium hat, which lowers rotating and unsprung weight on a disc this size. It measures 390 mm across and 36 mm thick, wears to a 33 mm minimum, and stands 64.5 mm tall on a 67 mm centering bore with 5 holes. The disc carries ECE R90 type approval and replaces OE A2314210612.
