My current Porsche has PCCBs and the one before did not.  I immediately noticed the difference in terms of brake feel and performance.  I was really amazed with the PCCBs and will not have anything else.  However, with time and wear and a few track sessions, the supersharp initial brake bite goes off.

Once the super bite wears off as a result of use and track work, do the PCCB's than brake similar to steel brakes? I am conflicted as to whether to order them for the GT3.  

 Nick , the PCCB always have a better "top end" bite (feel while slightly applying) compared to the steel - but trust me in saying that there is NOTHING wrong with the steel ones. For me it's just a option for those who want less unsprung weight (real benefit) and don't care about costs. Most frequent track-users have steel and are perfectly happy with it. You're tires will blow first before even the steel give up (correct track brake fluid is more the issue) So safe the money - Porsche brakes are amazing in any case !
