Dynamic Friction 830-73031R Disc Brake Rotor - Front Right

Overview

The Dynamic Friction 830-73031R is a vented disc brake rotor with a slotted and drilled surface, built for direct replacement applications that require precise fitment and consistent braking performance. It is compatible with 2004-2009 Audi S4, front right, and uses a directional brake surface for proper rotation-specific installation.

Part number 830-73031R features a plain disc finish, Geospec silver gray hat finish, and a rust-resistant coating to help maintain appearance and service life. The 345 mm outside diameter, 112 mm bolt circle, and 5-lug pattern support accurate OE-style fitment.

Key Features

• Vented rotor construction for improved heat management.
• Slotted and drilled braking surface for directional operation.
• Rust-resistant coating with Geospec silver gray hat finish.
• Plain disc finish with OE-style dimensions and 5-lug mounting.
• Fits 2004-2009 Audi S4, front right.

Detailed Description

Dynamic Friction 830-73031R is part of the DFC Geoperformance Rotor - Drilled and Slotted line, a rotor family focused on performance-oriented braking hardware with application-specific sizing. This rotor uses a vented design, directional surface pattern, and drilled-and-slotted braking face to support stable braking characteristics under repeated use. The 345 mm outside diameter, 68 mm center hole diameter, and 112 mm bolt circle help ensure correct alignment on the intended application. Fits 2004-2009 Audi S4, front right, and the part number 830-73031R should be verified against the vehicle before installation.

What It Helps Address

• Brake fade from heat buildup during repeated stops.
• Uneven rotor surface wear on the braking face.
• Corrosion on exposed rotor surfaces.
• Fitment issues caused by incorrect diameter or bolt pattern.
• Directional rotor mismatch during brake service.

Installation Notes and Tips

Confirm rotor orientation before installation because this rotor uses a directional braking surface. Verify disc diameter, center hole diameter, bolt circle, and lug count against the existing brake hardware. Clean the hub mounting surface before installing 830-73031R to help maintain rotor runout control and proper seating.

Quality Assurance

Dynamic Friction Geoperformance rotors are engineered with application-specific dimensions and protective surface treatments for consistent service fit. Part number 830-73031R is built to match the listed Audi S4 application and should be checked against the vehicle’s brake specifications before use.
