The great PCCB debate

[Mad Scientist]

I’m in the market to change my GT4 for a GT3. Ive never had any issue with the brakes on the Cayman on track, but I don’t do long sessions. The question is, are the PCCB on the GT3 a real step up in performance? Are they worth having with the extra poke of a GT3?

I can say now, unsprung weight isn’t relevant to me. I’ve all the finesse of a walrus. I could drive round Silverstone in Timberland boots and not notice the difference from some nomex dancing slippers. I wouldn’t notice the reduced mass.

Purely performance wise, are the PCCB really worth the cost, or are they just a nice match for yellow seatbelts?

Wow, lots to read there!

I do a lot of track days so I think steel seems to have the edge.

That said, getting a PCCB car and putting some steel rotors and aftermarket pads on sounds interesting.
I’m suprised at the cost. I used to sell Alcon and AP rotors when I had a small rally parts business. Are these kits using the PCCB bell with a steel rotor, or is that not being done?

Also, how do Porsche view that warranty wise? If my engine blows up, are they going to tell me it’s down to my brake rotors?
