Lewis,
Great Car! I am about to place an order and I am waffling on brakes. Not really a fair comparison, but how do you find the brake feel vs. your GT3? Would you go to PCCB if you had the option?
As follow up on the steering issue, you can read all the details for yourself in the 991 forum, but basically the electric steering introduces a DC motor and belt drive in place of the hydraulic assist. The rack and column are still there (no by wire steering), but the rack can only move when the DC motor turns (my read). The motor senses the input from the driver and reacts to provide assistance in a similar way to the hydraulics. But its all done via sensors and software rather than hydraulic pressure and relief valves. So the programming is the key to balance effort vs. feel.
Best,
Mike

Thanks for the comments on the steering.

Maybe's it's the nice YELLOW cailpers that I love on silver, white cars with dark interiors. Cool look.
If I order a 981 it will probalby be White / Silver over Blue interior with PCCBs

SUPER nice color combo Lewis but I guess I'm partial. Now my BIG question for you on changing from your 2010 GT3 to your 981 is HOW DOES IT DRIVE? The GT3 is a passionate emotive car. What about this beauty? Does it growl and make you grin?
Love my TT but always looking...

The 981 is a wonderful sports car that is very at home on the street and can be a competent track car. The GT3, IMHO, has no business driving around town. It is, however, the absolute best car you will ever drive FLAT OUT. Nothing comes close and the GT3 is the ultimate driving experience. Its a California Cab. The 981 is a fine aged Burgundy
I will own another GT3(RS)

I promised myself that I wouldn't compare this car to the GT3 and I don't think anyone should even try. They are very different cars tuned for very different purposes.

What PCCBs do give you is fade resistance. You can pound out hot lap after hot lap without having to worry about brake fade (within reason, of course), and that's where PCCBs shine. The irony is that you do NOT want PCCBs if you're going to track... While the rotors may last "forever" on the streets, you'll quickly eat through them on the track and they're mighty expensive.
If what I've heard (from multiple people) is true, then I suspect that your impression may be A) placebo effect, or B) due to the heavy weight of TT. Remember that TT is a pretty heavy car and it takes more force to slow it down.

From what I heard, PCCBs do not give you more stopping power. I've been also told that this is a common misconception.

I have officially decided to throw in the towel on my PCCBs. After only 5 track days, they are showing very early signs of wear. I'm converting to steels so I can run track pads. I'm saving the PCCBs rotors for the day that I retire the spyder from the track.

+1 on fade ressistance
But, everything I've seen says that PCCBs outlast iron rotors (with the same use - street or track), but that doesn't help with the value proposition.
The only way I can imagine improved 'stopping power' from PCCBs is if the lower unsprung weight allows better tire contact with a rough road/track.
Joe,
Please don't forget to let us know if the swapped rotors/pads gives a firm(er) pedal, or if there's no change. The setup you're going to will use the PCCB calipers, right?

Yes, still using the original PCCB calipers.
