991 GT3 customer shaves 2 seconds off lap time with our AP Radi-CAL Brake Kit


Our Essex Designed AP Racing Radi-CAL Competition Brake Kit has caused a huge splash in the 991 GT3 community. Our system addresses many of the weaknesses of the OEM system, with some of the major ones being:

  • Eliminates the need to remove the caliper for pad changes
  • Saves 33 unsprung lbs. vs. OEM iron brakes and weighs almost the same as the OEM PCCB system
  • AP Racing Radi-CAL with durable, ventilated stainless steel pistons (no ceramic piston caps to break) with anti-knockback springs
  • Allows for the preservation of pricey OEM brake components
  • Huge array of brake pad options from all major pad manufacturers
  • Clears OEM 20" wheels without a spacer
  • Every component designed to resist the heat of extended track sessions

One of our customers recently had Parkhaus1 in Miami install our system on his GT3, and subsequently took it out to Homestead Raceway for a shakedown. A couple of his comments:

"I feel I can modulate brake better and improved trail braking and brake release. Car more stable turning in and earlier on throttle. But want to see what data shows."

"Lots of adjustment as the weekend passed and interestingly, still dropped 2 seconds on my lap times. No other mod on car since last time."

Garage mates for the weekend. :)
