Porsche 718 GT4 owner sets personal best at Sonoma after swapping to AP Racing Brakes


We recently received some feedback from a thrilled 718 GT4 owner who dropped his factory PCCB setup in favor of our AP Racing by Essex Parts Radi-CAL Competition Brake Kit.

Our AP Racing by Essex brake products have become the recognized standard among Porsche car owners who are serious about tracking their car. Why? Because we've been able to improve upon the factory brakes in every conceivable manner, including convenience, fade resistance, longevity, weight reduction, wheel fitment, and long-term running costs. These improvements translate into faster lap times, fewer problems and headaches, substantial financial benefits, and more fun at the track! Please see the owner's comments below about how our system stacks up vs. the OEM PCCB brakes.

  • Your experience level & driving history (e.g.- I have been tracking cars for 10 years with SCCA, etc.)

3 years track experience, but I am doing about 20 days a year and have done SCCA school.

  • How have our brakes changed your driving experience?

I swapped out PCCB on my GT4 with the AP BBK set and I have significantly more brake feel and modulation, which has helped trail braking tremendously.

  • Problems that the brake kit solved (e.g.- pad fade, disc cracking, soft pedal, etc.)

Easy pad changes, bigger pad thickness, modulation ability and ability to run 19" wheels on my GT4.

  • Favorite product feature

easy pad changes

  • Comparison to other products you’ve tried in the past

None really other than comparison to PCCB, which Essex has documented well to customers.

  • Customer service by Essex before and after initial sale

very friendly and fast response.

  • Documentation and ease of install

shop did it for me and didn't note anything.

  • Would you buy it again, and would you recommend it to a friend?

absolutely. I have a 992 GT3 on order and I will be going with AP Racing and Essex again.

  • Anything about the product that you think could be improved?


  • Race or event wins on our brake kit

Personal bests at Sonoma.
