Staying in front can be every bit as demanding as taking the lead.
At AP Racing, yesterday's knowledge, know how and experience provide the platform for today's development. Building on success, AP Racing is constantly exploring new systems, techniques and materials in a continuous quest for further improvement.

“Radi-CAL” is a blanket term used to describe AP Racing’s patented asymmetrical brake caliper design. Radi-Cal technology is grounded in Computer Aided Design (CAD) and Finite Element Analysis (FEA), and allows for organic, alien-looking designs that are a radical departure from conventional caliper designs of the past. Radi-CAL's are widely considered the pinnacle of current brake caliper technology. Since their inception in 2007, these revolutionary calipers have amassed a lengthy string of race victories at all levels of professional motorsport, while redefining brake performance expectations. 

The key benefits of the Radi-CAL design:

  • Massive Stiffness Increase- A 30+ % increase in both static and dynamic stiffness vs. conventional calipers allows for far less deflection under load, which means superior pedal feel & modulation, more even pad wear, and longer caliper service life.
  • Considerable Mass Reduction- Removing all extraneous caliper mass lowers the caliper weight, despite the huge stiffness increases.
  • Optimized Airflow- Air moves around and through the caliper more efficiently, providing superior heat evacuation and cooling.
  • Efficient Packaging- The asymmetric caliper profile and internal fluid porting allows the caliper to fit into tighter spaces.

 

Brake Pads in A Commonly Available Shape


The basic pad shape for the CP94X caliper was created by AP Racing many years ago, and is used by a wide range of racing calipers today. They're available in just about every popular racing compound on the market. That means you’ll never end up in a pinch without pads.
