Hello all. Got the 997.2s up for sale and actively looking for a gt3.

I’ve been dismissing the cars with pccbs because of the general consensus that if u track the vehicle you want metal rotors.

But it as I think about it, it seems there are alternative rotors out there so maybe I should get one with pccbs, shelf the rotors and just replace with metals. If I ever go to resell the vehicle it may be wise to have the pccb system

Im I thinking wrong? Also since I will most likely be purchasing the right vehicle out of town, would the best place to do a PPI at the dealer, esp to inspect the rotors?

Are girodiscs the preferred replacement? Is it simply bolt on replacement? Or is it more involved?

Thanks!

daveo4porsche

your plan is sound and not uncommon

I have my PCCB's nicely stored on a shelf with zero track miles on them
I got the direct replacement gyro-discs and they work great and last a long time - there are also other excellent options in all price ranges

good luck with your purchase - PCCB's are great for non-track cars and a lot of people prefer them when purchasing a 911 GT3 that is rarely tracked.

PM ...I have a set of Girodiscs from my 991.1 GT3 that i sold

PCCB are great on the street and the track...but since they are so expensive to replace a lot of people take them off. I only do just about 4 de a year so I'm leaving my pccb on for now

ipse dixit

There is absolutely no reason to fear tracking with the Gen III PCCBs on the 991 GT3/RS cars.

Is this bizarro world?? The whole drivers of PCCB in the first place are reduction in unsprung weight, better agility, and increased stopping power...and ZERO fade resistance. WHY WOULDN'T YOU WANT THIS ON THE TRACK...??? One of the main purposes is to reduce lap times!

If you don't track with PCCB installed, this is like dating Heidi Klum and not removing her bra.

Or buying a brand new stove and not cooking.

You get the jist.

Drive the damn car.

I've tracked my 14 GT3, 16 RS and now my 19 RS with PCCBS. I burned thru a set on the 16 RS and replaced them with Surface Transforms rotors. I did 6 track days on the 19 RS PCCBs and swapped them out for the ST rotors. STs can do approximately 50 track days and can be refurbished up to 5 times at $600/rotor. STs run quite a bit cooler than PCCBs, thus extending pad life. In addition you can run more aggressive pads like the RSL 1. A set are significantly cheaper than the PCCBs at $13,000. Still crazy expensive, but becomes very competitive when you consider 250 track days for $25,000 with refurbishment.

It's tempting. But two questions:

1. Full set from ST = $9,000 GBP. Full set from USA distributor = $13,000 USD. There's a $2-3K difference in price. I wonder why.
2. 200 degrees cooler than PCCB? Brakes work by converting motion into heat to stop the car. Cooler brakes strikes me as a less stopping power, no? This question is more just my own curiosity and not really questioning the validity of the product. I would think brakes that run hotter would stop better because they're converting more kinetic energy into heat.

Would be great to get them at 9k! You are going to have Gavin at Autoquest about U.S. pricing. He can also answer the question regarding temps and stopping power. The performance is outstanding, especially since there is a wider variety of pads available so you can choose a pad that matches your driving style. I find trail braking is easier with the STs. Peter (TrackCar) has the most experience with these, he seems to be a huge fan.

To be clear, 9K GBP vs 13K USD. 9K GBP = $11,400 USD.

SanDiegoDavid

Must be the margin for US distributor.

From STs website:
While conventional carbon-ceramic brake discs use discontinuous (chopped) carbon fibre, ST interweaves continuous carbon fibre to form a 3D matrix, producing a stronger and more durable product with 3x the heat conductivity compared to our competitors; this reduces the brake system operating temperature, resulting in increased life of components with the same brake performance.

ST carbon rotors are superior to Porsche PCCB. If you can afford it do the ST rotors. Guys at the track rave about them

ThEnder

At $13k for a full set, they are considerably cheaper than replacing PCCB rotors. Why not run through stock PCCB and replace with ST when needed?

Probably people worried about resale. Always a bit of a gamble when you attempt to sell a car with aftermarket parts and easier with stock parts on it.
