I've since fitted 350mm Sebro disks all-round (997 turbo) with regular Pagid road pads with the standard calipers with 10mm spacers and high tensile bolts.

I have installed 997.1 turbo calipers and discs to all 4 corners, I had no faith in the original 996 turbo brakes, in fact quite terrifying at times!

I fitted decent pads after that and then no fade again for the next test.

I also flushed the system, fitted new stainless brake hoses and refilled with ATE performance fluid :thumb:
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

There's no difference to Pedal travel as the total piston area is the same, but it uses a larger swept area on a bigger radius with better heat management.
Performance in what way? I went from 330mm disks and turbo calipers to 350mm disks and GT3 calipers. I also run some big front brake ducts. GT3 RS I think but not 100% sure.
The performance between them under the majority of circumstances was more down to what pads were fitted than anything else. The turbo ones with decent pads would do 13 back-to-back emergency stops from 70mph with no fade at all. The GT3 ones did see fade under the same test, but not sure on the pads used. I fitted decent pads after that and then no fade again for the next test.
It is more about a larger thermal mass than anything else. You will have slightly more forward brake bias with these as well.
I fitted them because I like the look of them, with good brake ducts, decent fluid and good pads there is not likely to be a real need for them unless you are doing some pretty hardcore driving.
If you are doing changes, I have a couple of 27mm master cylinders available to give you a slightly stiffer pedal.

Standard turbo brakes are utter pap. Might as well put two blocks of wood either side of the disc. My mum's fiesta stopped better. It was embarrassing, I let my brother in law drive my Porsche and the first thing he mentioned was the terrible brakes. I used to brake twice as early before junctions as I had no confidence in them.
There is thread after thread of wooden brakes comments with replies saying they'll stop if you stand on them. I've been weight training all of my adult life so it's not like I was short on a bit of leg strength.
I fitted GT3 6 pots with standard 997 discs and performance friction pads. I'll change the pads as they squeel, but the braking performance was like switching the light on in a cellar.
Do it, you won't regret it. I'll get some decent discs and it'll be even better.

Best mod I've ever done. It's the brakes the car should have had.
I had them on my car when I bought it...I think they were a bit pooh too but you get used to them.
I kind of like them now, more because they look so damn cool under the hollow spokes 8)
:grin:
...I think the brakes (new all around 1000miles ago) complete with new brake fluid are crap tbh...my Honda jazz brakes have more feel and bite?!
I am thinking about changing the pads in an attempt to discover the fabled 911 braking performance...
I recently replaced the rear disks and pads on my C2, the inner faces were corroded but plenty of meat on them. I was really suprised at the difference.

these are so much better, I have not changed the brake fluid reservoir/master cylinder as some seam to think you must, it may be even better if you do :dont know:

these work great now
I hated the brakes on my car. I've since fitted 350mm Sebro disks all-round (997 turbo) with regular Pagid road pads with the standard calipers with 10mm spacers and high tensile bolts.
Night and day difference and not expensive. I already have the extra brake duct deflectors front and rear. If I want even better braking, I'd go for Pagid RS29.
I fitted the GT3 6 pots to mine with 350mm 997 turbo discs and RS29 pads, cracking mod. Stops better than my Ferrari 488 on 400mm carbon ceramic brakes. You won't regret it but choose the right pad and disc combo.

Yes, Pagid standard road pads. Sebro discs front and back.
All from Eurocarparts (or carparts4less).
Both companies have discount codes going at the moment, so take 14% off the CP4L prices.
If I decide to track the car, I'll put Pagid RS29 on. Perhaps Brembo HP2000 or Performance Friction for a more road biased setup, as the RS29 can squeal if they're used too lightly I've been told.
