To name a few.One is brake squeal, the other is easy to pinch pebbles.I think that is the point.
As for brake squeal, I don't mind it, and I'm more the type of person who thinks it's typical of Porsche brakes, so it's not something I personally complain about. However.PCCB is more prone to squeal than cast iron discsIt is a fact. The instruction manuals also mention the PCCB squeal as a precaution.
In the case of my unit, it is particularly prone to appear, especially after repeatedly braking a little harder, especially on winding roads. However, when driving in town afterwards, the problem naturally subsides after a while.
Secondly, it is easy to catch pebbles. This is because I sometimes drive my GT3 on rough roads.After passing a gravelly road, for example, there is often a crunching sound from the brakes.The probability of that happening seems much higher than with cast iron brakes. Specifically, I don't know where they get pinched, but they too naturally settle after running for a while.
The PCCB's intense braking power and ease of control are outstanding.It also seems clear that it has had no small positive impact on ride quality and handling.
On the other hand, there are still some aspects of durability that I can't say for sure, but I don't think there is any need to be so nervous when driving lightly on the circuit a few times a year, as I do.(It may be a different story at a circuit like Fuji, which is very demanding on brakes. This remains to be investigated.)
If you're asking me if it's worth the price, I guess this depends, at least for me.When you buy a Porsche in the future, if you buy a 911, Cayman, Boxster or other sports car, this is one of the options you should definitely add!I feel that it is.
