Product Details

The DFC Geoperformance Rotor line focuses on drilled and slotted brake rotor construction for drivers who need consistent braking performance and a precise OE-style fit. This rotor measures 73.6 mm in height, uses a 16.5 mm bolt hole diameter, and is configured as a directional vented rotor for the front right position. The 830-31112R is listed for BMW 335i, BMW 340i, BMW 435i, BMW 440i, and ActiveHybrid 3 applications across 2013-2020 model years, including standard disc and dimpled slotted disc configurations noted in the fitment data.

Compatible With BMW 335i, BMW 340i, BMW 435i, BMW 440i, and ActiveHybrid 3 front right brake applications, this rotor is a direct-fit option for drivers searching for a BMW front right drilled and slotted rotor, a 370 mm vented BMW brake rotor, or Dynamite Friction 830-31112R replacement rotor fitment.

What It Helps Address

• Brake pulsation from worn or uneven rotor surfaces
• Reduced braking consistency during repeated stops
• Corrosion on exposed rotor surfaces
• Rotor replacement needs for front right BMW brake service
• Fitment matching for drilled and slotted BMW performance brake setups

Installation Notes and Tips

Verify rotor dimensions, bolt circle diameter, center hole diameter, and thickness before installation. This rotor is listed for the front right position only, so confirm side-specific fitment before ordering. Check pad condition, caliper operation, and hub surface condition during brake service to help ensure proper rotor seating and even wear. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Dynamite Friction’s Geoperformance Rotor line uses a rust resistant coating and Geospec Silver Grey hat finish to support long-term appearance and corrosion resistance in brake service applications. Part number 830-31112R is specified with detailed dimensional data to support accurate fitment selection for BMW front right rotor replacement.
