R1 Concepts 2551-0606-00 Optimum OEP Ceramic Rear Brake Pads

The R1 Concepts Optimum OEp Ceramic Rear Brake Pads (2551-0606-00) are a direct OE replacement brake pad engineered to deliver factory-level stopping performance for select Lexus, Mitsubishi, and Toyota SUVs and trucks. Formulated using an Original Equipment Manufacturer ceramic compound, these rear pads are designed for everyday drivers who demand reliable braking without excessive noise, dust, or rotor wear.

R1 Concepts uses the same positive molding process found in OEM brake pad manufacturing, combined with a post-cure process for enhanced durability and a consistent friction coefficient throughout the life of the pad. Rubber-coated OE-style anti-squeal shims are included to minimize brake noise and vibration, while the pre-scorched friction surface helps promote a faster and easier bed-in period right out of the box.

Key Features:

• Ceramic OE Formulation: Matches original equipment friction characteristics for safe, predictable stopping power
• Low Noise & Low Dust: Ceramic compound produces minimal brake dust and operates quietly under normal driving conditions
• Rotor-Friendly Design: Proven to extend both pad and rotor service life compared to more aggressive compounds
• 100% Positive Molded: Same manufacturing process as OEM pads for consistent feel and structural integrity
• Pre-Scorched Friction Surface: Promotes faster pad bed-in and immediate brake response upon installation
• OE-Style Anti-Squeal Shims: Rubber-coated shims reduce noise and vibration for a quieter ride
• Post-Cure Process: Improves pad durability and maintains a consistent coefficient of friction at operating temperatures
• Low Copper Formula: Environmentally friendly formulation meets California and Washington low-copper requirements for 2021/2025
• No Modification Required: Direct bolt-on fit — no hardware modifications needed for installation
• 100% Asbestos-Free: Safe and compliant with modern material standards

Designed for passenger vehicles, light-duty trucks, and SUVs used in daily driving conditions, the R1 Concepts Optimum OEp series rear brake pads are backed by a 1-year warranty against manufacturer defects. Compatible with select 1993–2017 Lexus, Mitsubishi, and Toyota applications including the 4Runner, FJ Cruiser, GX460, GX470, Land Cruiser, LX450, Montero Limited (Mexico), and Sequoia.
