R1 Concepts 2551-0154-00 Optimum OEP Semi-Metallic Front Brake Pads

The R1 Concepts Optimum OEP Semi-Metallic Front Brake Pads (Part# 2551-0154-00) are a direct-fit replacement brake pad set engineered to deliver reliable, consistent stopping performance. Designed as a high-quality OE-style replacement, these pads are well-suited for everyday street driving and provide a confident pedal feel across a wide range of operating temperatures.
