The DFC 920-31091D rear left brake rotor is engineered for the 2008-2011 BMW 1 Series M, providing dependable stopping performance, consistent braking control, and long-lasting durability. 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.
Each 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.
Built 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.
