Prepping your Miata or Fiat for the track this spring, or maybe just adding a nice dose of boost? You’ll need some serious whoa to accompany all that go. Our incredible new AP Racing Radi-CAL Competition Brakes will drop your lap times, increase your consistency, and lower unsprung weight, all while reducing your long-term running costs.

“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.
