Constructed from premium G3000\/G11H18 iron castings, this drilled rotor offers the strength and stability needed for demanding street and performance-driving applications. Its original-equipment vane configuration supports efficient heat dissipation, helping manage braking temperatures during repeated stops.\u003c\/p\u003e\n\u003cp\u003eEach DFC 920-31091D rotor is precision mill-balanced to promote smooth braking with minimal vibration at any speed. The fine-turned 16 RMS finish supports improved initial rotor and brake pad break-in, helping establish consistent contact between the friction surfaces. Drilled construction assists with heat management and surface cleaning, while the Geomet coating provides high-performance corrosion protection for enhanced appearance and durability.\u003c\/p\u003e\n\u003cp\u003eBuilt to stringent manufacturing specifications, this rear left rotor maintains a maximum disc thickness variation of 0.010 inch and maximum lateral runout of 0.050 inch. These precise tolerances help support even pad wear, stable pedal feel, and reliable braking performance. Designed as a direct-fit replacement for the specified BMW application, the DFC 920-31091D combines OE-style fitment with upgraded materials and finishing for confident everyday driving and spirited use.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePremium G3000\/G11H18 iron castings provide strength, stability, and durability\u003c\/li\u003e\n\u003cli\u003eOriginal-equipment vane configuration supports efficient heat dissipation\u003c\/li\u003e\n\u003cli\u003ePrecision mill-balanced for smooth stopping with minimal vibration\u003c\/li\u003e\n\u003cli\u003eFine-turned 16 RMS finish improves initial rotor and brake pad break-in\u003c\/li\u003e\n\u003cli\u003eDrilled design helps manage heat and maintain consistent braking performance\u003c\/li\u003e\n\u003cli\u003eGeomet coating provides high-performance corrosion protection\u003c\/li\u003e\n\u003cli\u003eMaximum disc thickness variation of 0.010 inch\u003c\/li\u003e\n\u003cli\u003eMaximum lateral runout of 0.050 inch\u003c\/li\u003e\n\u003cli\u003eRear left direct-fit brake rotor for the 2008-2011 BMW 1 Series M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFC","offers":[{"title":"Default Title","offer_id":67588974707004,"sku":"dfc920-31091D","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1865\/9007\/files\/510c2482a31b4bc84e9dc18ee76673f0L_7cab5522-0cf2-428b-b130-5e81ab850e21.jpg?v=1790557863","url":"https:\/\/necycleshop.com\/products\/dfc-08-11-bmw-1-series-m-rear-left-drilled-hi-carbon-alloy-geomet-coated-rotor","provider":"NE Cycle Shop","version":"1.0","type":"link"}
