Dynamite Friction 4512-13055 Disc Brake Kit - Front

Front Brake Kit for Subaru WRX and STI

The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware, part number 4512-13055, is a front disc brake kit built for OE-style service replacement. It combines coated rotors, ceramic pads, and matching hardware for Subaru WRX and Subaru WRX STI front brake service.

• Front disc brake kit with rotors, pads, and hardware
• DFC GEOSPEC coated rotors with silver-gray corrosion-resistant coating
• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pads for reduced initial break-in time
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Non-directional rotor finish for smoother pad bed-in and quieter stops
• OE-spec cast iron rotor construction and tight machining tolerances

DFC GEOSPEC and 5000 Advanced Brake Pad Line

The DFC GEOSPEC rotor line is designed for drivers who want a coated replacement rotor that resists rust better than conventional paint or zinc finishes. Each rotor is processed dry and ready to install, which helps reduce prep time during brake service. The 5000 Advanced pad line uses post-cured, scorched ceramic friction material to promote stable braking performance and consistent initial bite, while the shim design helps reduce brake noise and vibration.

Part number 4512-13055 is also a practical choice for Subaru WRX front brake repair and Subaru WRX STI front brake replacement when you want a complete service kit in one package.

Compatible With

• Fits 2020 Subaru WRX, front, Brembo Performance Braking System (4-piston front calipers)
• Fits 2013-2017 Subaru WRX STI, front
• Fits 2005-2014 Subaru Impreza, front

What This Kit Helps Address

• Brake noise during stops
• Uneven or premature pad wear
• Rotor rust and surface corrosion
• Longer brake service time from rotor prep
• Reduced braking consistency from worn pads and hardware

Installation Notes and Tips

Install on the front axle only and verify caliper and rotor application before service. The coated rotor surface is ready to install and the coating is removed naturally by the pad during normal braking. For best results, follow a proper pad bed-in procedure after installation and inspect caliper hardware, slides, and mounting points during brake service.

Quality Assurance

DFC machines each rotor to tight tolerances, applies a non-directional finish, and inspects critical dimensions before release. Vented rotors are balance-checked and corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship.
