Some things you have to try at least once. Run a set of PCCBs on track and feel for yourself the difference. It's revealing and the lightness (esp. on/off kerbs) is something even hamfisted Ams like me can feel.

$'s surely are a consideration. But do consider that in the context of a $200k+ car... everything's relative.

With proper pre-track prep and on-track care, one or two track events ain't gonna kill your Gen-3 PCCBs. Go do it!! I know I will.

+1

Once you've done PCCBs you can't go back to irons.

I agree.
Never considered it because steel works OK and the cost of PCCB was too much for me, but the lightweight and cooler brakes are awesome.

I have ST but same thing, I can't go back

I did 2 track days on pccb several ~5 years ago. Loved it. Loved it. However given it was oem PCCB, $$$ to replace, i put them in the shelf. I'm going bakc to CCB after reading your post on ST having $500 refurb cost per rotor.
At that price, no point in irons. CCB > in every way.

New steel rotors are $3500?
My math is that every 20-30 days the ST rotors cost $2000.
and they cost $12K so they depreciate every 20-30 days by $2000 assuming you can refurb 5X.

That’s 120-180 track days.
ideally that would be about 4 years LOL.
Pretty sure the car is tired by then

I got 34 track days out of PCCBs on my 2014 GT3 but only 24 days out of the PCCBs on the RS. Like Peter I have gone with ST rotors, they perform the same as the PCCBs but run cooler with much longer pad life. They also have better pedal feel than the PCCBs making trail braking easier. OEM replacements rotors were estimated to be 32k fir me , so the 14k for the STs was a no brainer.

Assuming that was the Gen II PCCBs, then you should give the Gen III version a try.

Not to say that the Gen III PCCBs are going to be as durable as OEM irons, but they are no where near as fragile as the Gen II iteration. Of course, YMMV.

They say the new RS has different spacing in the PCCBs to increase response, and this is just in relation to the .2 GT3. I'm hoping to get the STs this Fall but wondering how they are going to deal with all the micro differences between all the generation of Gt3s and RS cars. Crazy how every slight difference changes these cars. Auto Quest is really putting a lot of effort into all their products so I'm sure they will figure it out.

ST are 12K but the rears should last forever.

Fronts should be OK for 5 refurbishments and 20+ track days in between the refurbs. Refurb is $500 per corner.
I'm on day 12 of being very hard on the brakes...
Sorry, but would you mind explaining what ST rotors are?! Thanks.

Do consider your own driving style and brake use pattern. At risk of stating the obvious, one driver getting X days at Sebring doesn't remotely translate to the same outcome for another. There's also your own performance progression: over time you are driving better and braking harder...

Extreme example: for many in Carrera Cup, the brand new steel rotors on a 0-mile 991.2 look very second-hand after just two days (~5 hours) of testing. Yet some chunk of the grid can see their rotors last well into round 2 even round 3...

Try your ceramics if you got them. Box 'em for steels if you're not hooked (insert evil face)

ST importer where I got mine:
https://www.autoquestcars.com/custom-11

+1 CREX, if you’re not pushing very hard or you’re on easier on the brakes tracks, the steel brakes are some of the best in the business.
Id suggest that you go PCCB when you can’t keep the pedal from going long only.

If I’d say that if that is the case the consistency is the biggest benefit of ceramics.
And at 10/10th they are a little faster due to weight..

Looks like ST offers a CCB upgrade for the irons and not much more than the cost of the factory option.

Are the OEM calipers identical between iron and PCCB (besides yellow paint)? Only difference being pads and rotors?

I went steel to ST.
Same calipers, Easy install, they did mine at the track in a couple hours.
