On the F87 that drum sits inside the hat, so the rear disc wears two ways at once — friction face from braking, drum from the shoes.\u003c\/p\u003e\n\u003cp\u003eOur rear pair is built like the front: a G3500 high-carbon ring on a 6061-T6 aluminium hat, bolted through stainless floating hardware. The drum surface is machined as part of the ring, so parking brake bed-in is the same as factory. 64.9 mm total height on a 75 mm centre bore, 5 bolt holes.\u003c\/p\u003e\n\u003cp\u003eMeasure the drum, not just the ring: this disc has two working surfaces, 380 mm at the friction ring and the drum bore inside the hat. A 370 mm rear disc from an F80 will bolt up and then foul the parking brake shoes.\u003c\/p\u003e\n\u003cp\u003eOE reference 34118072019 \/ 34118072020 · Minimum thickness 26.0 mm · Bolt holes 5\u003c\/p\u003e\n\u003cdetails\u003e\n  \u003csummary\u003e▸ \u003cstrong\u003eFitment check\u003c\/strong\u003e\u003c\/summary\u003e\n  \u003cp\u003eF87 M2 rear, 380 × 28 mm with drum parking brake — OE 34118072019 and 34118072020.
