AP Racing 2-piece J Hook Discs


OEM brake discs are typically designed with a series of inherent compromises. They are designed to be quiet, easily mass produced, and above all cheap. Unfortunately these design objectives aren't exactly in line with the goals of most enthusiasts, who crave high performance benefits such as crack resistance, maximum airflow, and the lowest weight possible.

AP Racing competition brake discs are designed without restriction, and only the absolute maximum performance in mind. With countless wins in Formula 1, NASCAR Sprint Cup, ALMS, DTM, and WRC, they are the clear choice when cost is no object. Fortunately, many of AP Racing's discs are more affordable than you'd expect with such a lengthy winning pedigree.
