Why upgrade to AP Racing Radi-Cal?

AP Racing Radi-Cal big brake kits have become to be known for their "race on Sunday, sell on Monday" mentality. In an era of high powered motorsports which sees very little technology making its way to the lower echelon of track and street vehicles, AP Racing has taken the bold decision to re-write the history books and bring that famous saying back. After many years of success in racing series' such as Formula 1, NASCAR, World Rally Cross, Indy, ALMS, Le Mans, and many more, AP Racing decided to bring the World Radi-Cal calipers to the masses. To bring this technology to the street, AP Racing once again reviewed their current big brake kit offerings and decided to improve upon every single aspect of the caliper.

Weight savings - By removing material where it wasn't necessary, and keeping the material only where it's actually required, AP Racing has been able to remove a considerable amount of dead weight. Additionally, in going with the pressure forged aluminum manufacturing process, the caliper is about 20% lighter than if it were to be constructed out of cast aluminum.

Strength - By using the pressure forged aluminum manufacturing process, the caliper is also 25% stiffer than if it were to be constructed out of cast aluminum. The caliper has been designed to only have material in key structurally integral areas so as to better manage the huge loads being placed on the caliper during hard braking on both the road and race circuit.

Design - AP Racing wanted to build a caliper that wasn't just structurally and technically ahead of the competition, but also in the looks department. They've succeeded in doing this by designing a caliper that is without doubt the best looking caliper in the big brake kit market.

Functionality - AP didn't want to simply build a great looking caliper that works well for the street; they wanted to build THE best looking caliper that would outperform every other comparable caliper in any environment it was placed into. To accomplish this, they paid close particular attention to how easy it was to swap out the brake pads. With the quick release pressure forged bridge pad, changes take a matter of minutes instead of hours like other big brake kits available on the market today. The internal seals of the caliper have been designed with extreme precision and are rated for supercars like the Bugatti Veyron, the Koenigsegg and the McLaren MP4-12C - vehicles that are put through the most extreme driving conditions and will undoubtedly see extensive high performance track use.

Every STILLEN manufactured AP Racing Radi-Cal big brake kit comes with everything you need to complete a full installation including the AP Racing Radi-Cal calipers, AP Racing high performance rotors (available in either J hook or cross-drilled and slotted patterns), high performance brake pads, billet aluminum mounting hats and full floating hardware (pre-assembled for easy installation), billet aluminum mounting bracket, braided stainless steel brake lines with correct conversion fittings when necessary and detailed installation instructions.

Each kit's design is based on the vehicle's GVW, heat index required at maximum speed and GVW while maintaining brake balance for peak performance and compatibility with O.E. Anti-lock braking and stability control systems. The goal is a brake system designed to manage heat properly in the most efficient way using components designed and validated specifically for a high performance track environment and everyday road use. The result is a big brake kit that offers track braking performance that is safe and compliant for your road registered vehicle.
