Designed for high-stress circuit use, demanding track days and high-speed road driving, they deliver exceptional heat dissipation and significantly improve rear-axle braking balance.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eTheir two-piece construction combines an ultra-lightweight anodised aerospace-grade aluminium bell with a high-carbon cast-iron friction ring through a floating bobbin system. This design allows the friction ring to expand and contract freely during thermal peaks, preventing warping, heat cracking and pedal vibration. Curved slots (Curved Slotted \/ SG Groove) continuously clear pad-outgassing and friction dust, maintaining responsive bite. Directional internal curved vanes maximise channelled airflow and radically reduce operating temperatures.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eSupplied as a complete, ready-to-fit pair (fully assembled rings and bells), they directly replace the original 370 mm rear discs while retaining perfect compatibility with the factory calipers.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"4\"\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"5,0,0\"\u003e\n\u003cb data-path-to-node=\"5,0,0\" data-index-in-node=\"0\"\u003eType:\u003c\/b\u003e Two-piece floating rear brake discs (complete assembly)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003e\n\u003cb data-path-to-node=\"5,1,0\" data-index-in-node=\"0\"\u003eSlot design:\u003c\/b\u003e SG Grooved (curved slots)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003e\n\u003cb data-path-to-node=\"5,2,0\" data-index-in-node=\"0\"\u003eVentilation:\u003c\/b\u003e Directional internal curved vanes\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003e\n\u003cb data-path-to-node=\"5,3,0\" data-index-in-node=\"0\"\u003eMaterial:\u003c\/b\u003e High-carbon cast iron with anodised aluminium bell\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003e\n\u003cb data-path-to-node=\"5,4,0\" data-index-in-node=\"0\"\u003eOuter diameter:\u003c\/b\u003e 370 mm\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,5,0\"\u003e\n\u003cb data-path-to-node=\"5,5,0\" data-index-in-node=\"0\"\u003eNominal thickness:\u003c\/b\u003e 24.0 mm (minimum thickness: 22.0 mm)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,6,0\"\u003e\n\u003cb data-path-to-node=\"5,6,0\" data-index-in-node=\"0\"\u003eComplete kit:\u003c\/b\u003e 2 brake discs (rear left and right)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,7,0\"\u003e\n\u003cb data-path-to-node=\"5,7,0\" data-index-in-node=\"0\"\u003eFloating construction:\u003c\/b\u003e Free thermal expansion to prevent warping and vibration\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,8,0\"\u003e\n\u003cb data-path-to-node=\"5,8,0\" data-index-in-node=\"0\"\u003eReduced unsprung mass:\u003c\/b\u003e Improves chassis response and suspension operation\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,9,0\"\u003e\n\u003cb data-path-to-node=\"5,9,0\" data-index-in-node=\"0\"\u003eSuperior heat dissipation:\u003c\/b\u003e Ventilation vanes designed to maximise airflow\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,10,0\"\u003e\n\u003cb data-path-to-node=\"5,10,0\" data-index-in-node=\"0\"\u003ePlug \u0026amp; Play installation:\u003c\/b\u003e Direct replacement for the original 370 mm components with no modifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"6\"\u003eNote\u003c\/h3\u003e\n\u003cp data-path-to-node=\"7\"\u003eAs these discs use directional curved ventilation, ensure that the correct rotation direction (right \/ left) is observed during installation.\u003c\/p\u003e","brand":"EBC","offers":[{"title":"Default Title","offer_id":62790878986570,"sku":"MP-FE-AU-0117","price":1206.42,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1054\/5761\/5178\/files\/MP-FE-AU-0117-1.jpg?v=1784793254","url":"https:\/\/shop.scuderia21.com\/en\/products\/dischi-freno-posteriori-componibili-flottanti-sg-grooved-370mm-per-bmw-m2-m2-competition-m3-e-m4-ebc-brakes","provider":"SCUDERIA21 LAB","version":"1.0","type":"link"}
