The stopping distance is limited by the available traction between the tires and the road, not the stock brake system. The stock system is already limited by that available traction when cold. So the new system will not show a significant difference under those conditions.

The difference is in repeatability of those stopping distances. As the stock system gets too hot and exhibits fade, an upgraded system better manages the heat and is able to dissipate it faster thereby maintaining consistant performance.

I think you need to better define your priorities.

What is it that you are looking for, best performance or longest life? Those are typically mutually exclusive.

I know of no serious track goers that run with PCCBs as they do not last long in that environment and the replacement cost is very high. If you are looking at only limited track use and mostly street driving they will be fine, and are the lightest option, thereby giving the most benefit to the ride and handling as well.

The Brembo upgrades are the next lightest and are also capable of being run harder at the track than either the original iron or the PCCB brakes. For serious track goers I would suggest slotted discs and racing pads.

The pads that are included in the kits are a very well rounded high-performance material that has high cold friction, a stable coefficient from cold to medium-high temperatures, reasonable pad and disc wear rates, and is capable of moderate track use.

The best system for your needs depends on your goals, car modifications, driving syle and skill level. Its not going to be the same for everyone.

The GT kits are available with either drilled or slotted discs, it is the choice of the customer, along with caliper color.

Honestly, it sounds like any of the systems would work well for you, since you are just beginning with track usage.

For PCCB's on the track, the best bet is to get some real ducting to the brakes to prolong their life.

They do stop better if you are pushing the car hard enough to fade the stock brakes.

Like you said, though, you probably don't need them.

Please read the previous posts. I have already tried to provide you with the information, and don't want to keep repeating myself.

The bottom line is that the PCCB's are great for street use but they don't stand up to abuse at the track.

I assume you are referring to a 997GT2?

This is a problem, along with the 997GT3 PCCB cars. The front upright uses a 225mm mount spacing (the calipers are basically the same as those on the Carrera GT) so it is almost impossible to adapt anything to it. We've got a couple things in the works, but it takes a while to develop when you have to design specific calipers and discs for the application.

For 996GT2 we have a number of options including 2-piece floating iron discs to directly replace the PCCB units, and full brake systems as well.
