Complete front AP Racing by Essex Radi-CAL Competition Brake Kit for various Porsche 911 - 992 and 991 models (non-GT3):

  • Iron discs are incredibly resilient under heavy track use, and replacements cost one tenth of PCCB ($600 vs. $6,000 per disc)
  • Shaves over 20 lbs. off the front axle vs the 992 Turbo / GTS iron brakes
  • Adds less than one pound per side of unsprung weight vs. the OEM Turbo S PCCB setup
  • Fits inside 19" wheels, which the OEM PCCB discs cannot do, allowing for additional unsprung weight reduction plus improved tire options
  • Our AP Racing Radi-CALs feature a removable bridge, making pad swaps far faster and easier than stock calipers
  • Commonly available AP Racing pad shapes provide a wide selection of brake pad choices to tailor system feel and performance
  • Removing the stock calipers and PCCB discs allows them to be preserved undamaged, retaining the vehicle's future resale value
  • Our systems typically trade hands on the used market at 65% or more of their original MSRP, lowering the long-term cost of ownership. Use them for a few years and recoup a large portion of your initial investment.
  • Designed to work with our matching rear 380mm Radi-CAL Brake Kit. For ideal brake balance, it is not recommended to pair with our smaller 365mm brake kits.
