The AP Racing Radi-CAL brake system is specifically designed for E46 M3. This groundbreaking brake caliper innovation introduces a revolutionary asymmetrical design, utilizing advanced Computer Aided Design (CAD) and Finite Element Analysis (FEA) techniques. The result is visually stunning calipers with a unique, organic appearance, breaking away from traditional designs.
Since its debut in 2007, the Radi-CAL system has dominated professional motorsport, achieving numerous victories across various competitions. By redefining performance expectations, these calipers have consistently proven their superiority.
The Radi-CAL design offers several distinct advantages that differentiate it from conventional calipers. Notably, it delivers a significant increase in stiffness, boasting over 30% higher static and dynamic stiffness compared to traditional calipers. This enhanced rigidity minimizes deflection under load, resulting in exceptional pedal feel and modulation, as well as promoting even pad wear and extending caliper lifespan.
In addition to improved stiffness, the Radi-CAL system achieves substantial weight reduction. By eliminating unnecessary caliper mass, these calipers become lighter while maintaining increased stiffness. This reduction in unsprung weight contributes to enhanced vehicle handling and overall performance.
Optimized airflow is another notable feature of the Radi-CAL design. The caliper's shape allows for efficient air movement around and through the caliper, facilitating superior heat evacuation and cooling. This efficient airflow management ensures consistent brake performance, even in demanding conditions.
The Radi-CAL system also excels in efficient packaging. The asymmetric caliper profile and internal fluid porting enable the caliper to fit into tight spaces without compromising performance or functionality. This versatility in packaging ensures compatibility with various vehicle models, including the E46 M3.
Discover the forefront of brake caliper technology with the AP Racing Radi-CAL system. With its exceptional stiffness, weight reduction, optimized airflow, and efficient packaging, these calipers redefine the limits of performance and reliability. Elevate your driving experience and unlock a new level of braking precision with the AP Racing Radi-CAL brake system.
