OBP Racing Series RS 4 Pot Brake Calipers - Pair

The OBP Racing Series RS 4 Pot Brake Calipers are built to deliver stable, repeatable braking in performance and motorsport conditions. Built for use on track and in high-demand driving setups, they combine strength, low weight, and efficient cooling to handle the sustained heat and pressure of hard braking. The forged aluminium construction and internal airflow design help maintain braking stability over repeated use, while the compact size allows compatibility with a wide range of wheel and disc configurations.

Here are the main features and the outcomes they deliver:

• Aerospace Grade Forged Monoblock Aluminium Construction: Manufactured through precision CNC machining from a single forged billet, this design increases structural rigidity and reduces flex under pressure, helping you maintain consistent pedal feel and reliable stopping power throughout hard use.
• 3kg Lightweight Body: Each calliper weighs just 3kg, significantly lowering unsprung mass, which improves suspension response and handling precision while contributing to more predictable braking performance in dynamic driving conditions.
• Hollow Body Internal Cooling Design: Engineered with integrated airflow pathways, this design enhances heat dissipation during continuous braking, reducing the risk of fade and ensuring consistent braking response throughout longer sessions.
• 56cm² Piston Area (38x41mm Aluminium Pistons): The piston configuration provides even pressure distribution across the brake pad surface, which improves braking balance and wear characteristics, allowing for smoother and more stable deceleration.
• Oxidised Grey Coating: The durable surface treatment adds corrosion resistance and heat protection, supporting long-term reliability and preserving performance in exposed or demanding environments.
• 330–355 x 28mm Brake Disc Compatibility: Sized to suit a wide range of disc setups, this compatibility allows for straightforward pairing with commonly used performance disc sizes, making installation simpler and helping maintain optimal braking output.
• M10x1 Fluid Port Thread: The standard sized fluid port thread supports easy connection with existing brake line systems, ensuring efficient fluid delivery and simplifying the setup process within custom or pre-existing braking configurations.

Built for use in applications where heat control, structural strength, and reduced weight are essential, the RS 4 Pot Calipers help you achieve consistent braking across a wide range of conditions. They support confident braking in scenarios where control, repeatability, and reliability are a priority. As a robust and high-performance addition to your vehicle setup, these callipers offer long-term value in both track environments and performance street builds.
