Dynamite Friction 4512-75055 Disc Brake Kit - Rear

Rear Brake Kit for Lexus GS, IS, and RC

The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit combines coated rear rotors, ceramic brake pads, and brake hardware in one service package. Part number 4512-75055 is built for rear brake service on select Lexus applications from 2013-2020.

Key Features

• Rear disc brake kit with rotors, pads, and hardware
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pads for reduced break-in time and consistent initial bite
• 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-style rotor machining and inspection for dimensional consistency

Product Details

The DFC GEOSPEC rotor design uses coated cast iron construction to resist rust and arrive ready to install without oil-cleaning prep. The rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions. The 5000 Advanced pads are formulated for stable friction performance and are assembled with shims that help reduce brake noise. Part number 4512-75055 is a practical rear brake service solution for Lexus GS350, IS350, IS300, RC350, RC300, GS300, GS450h, GS200t, IS200t, and RC200t rear brake applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear brake noise, squeal, and vibration
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from fatigued hardware
• Longer stopping distances caused by worn friction material
• Brake pulsation from rotor surface wear or inconsistency

Installation Notes and Fitment

Compatible with rear brake service on 2013-2020 Lexus GS350, rear; 2016-2020 Lexus IS300, rear; 2014-2020 Lexus IS350, rear; 2016-2020 Lexus RC300, rear; 2015-2020 Lexus RC350, rear; 2018-2019 Lexus GS300, rear; 2015-2018 Lexus GS450h, rear; 2016-2017 Lexus GS200t, rear; 2016-2017 Lexus IS200t, rear; and 2016-2017 Lexus RC200t, rear. Review the fitment notes for F Sport and front-rotor configuration details before ordering.

Before installation, confirm rotor size, caliper hardware condition, and pad orientation for the specific vehicle configuration. Clean the hub mounting surface, torque fasteners to factory specification, and follow a proper brake bed-in procedure after installation.

Quality Assurance

DFC states that each rotor is inspected for critical dimensions and balance, and the rotor set includes a 12-month warranty against defects in material and workmanship. The pad formulation is post-cured and scorched to support stable friction performance from the first stops.
