Hey Adam,

If your buddy would simply mark-out any of his personal information on his Carbotech Order/Receipt and let you post the picture here it would be greatly appreciated.

Thanks for the assistance,
Terry

For a 2021 GT4 the pad part #'s are as follows:

Hawk: HB848 Front and HB850
Carbotech: CT1741 Front and CT1740 Rear
Ferodo: FCP4664 Front and FCP4665 Rear
PFC: 1773 Front and 7727 Rear

Don't recommend Hawks for anything but street use which is fine in this case. The Ferodo DS2500's as mentioned above are out of stock pretty much everywhere right now, and Europe is on summer holiday until the end of the month. PFC doesn't offer the z-rated compound in this pad shape. Not as familiar with Carbotechs.

I just spoke with Carbotech. I think this was essentially news to them so we'd guess the other 2021 owner has the too wide shape like yours as well. Keep in mind that Carbotech is a bit more 'handmade' as opposed to mass produced so it might be a bit different.

D1741 is too wide as shown.

We'll get the GT4 shape created/designed and correct in Carbotech for sure. Just need to clarify a few things before trigger gets pulled.

Interestingly Ferodo makes the shape in 62mm pad depth i.e. fits the GT4 better than the 99x GT3 brakes

aigh!

My friend installed Carbotech: CT1741-1521 and CT1740-1521 on his 2021 GT4 months ago and has been happy with them, no issues.

I've used Carbotech for years on my other car so it's good to see them getting mentioned here.

Just note that they aren't exactly low dust. Brake dust is a fact of life with steel brakes.

I second both of these statements. Very happy to see Carbotech and looking forward to using them again myself.

So which pads provide the best balance of low dust and good street performance?

So much time invested from so many people…

OP, should have asked each of us for $50 and ordered the PCCBs

tigerhonaker

Actually money was not my deciding factor on ordering my GT4 without the Ceramic Carbon Brakes.
I just wanted to avoid the chance that the PCCB rotors might get damaged while the GT4 was in for service.
Of course one would think if your using a Porsche Dealership those Techs would already be well aware of that and be Super-Careful not to Chip the PCCB rotors.

And lastly this is a street driven GT4, not a track GT4 !!!

The other thing to me was seeing reviews as well as videos where the PCCB brakes had the tendency to produce Brake-Squeal.
And personally I hate that ^^^

So, guys I went with the steel brakes and figured the simply solution was to just replace the stock brake pads with those that produce a lot less brake-dust.

I never ever thought it was going to turn into a damn nightmare for something as simple as Correctly fitting brake-pads.

Live and learn,

All brakes squeal if not bed in or driven properly. I’ve had both iron and ceramic that were quiet.

Carbon Ceramics are robust, super rare they ever get “chipped”..you’d read about here if common.

Finally you get the CCBs for the street for looks and dust management. Serious track cars get iron because of consumable cost.

tigerhonaker

Well my Good-Man actually as the months rolled by I did think that maybe I should have gone with the PCCB.
But ...............
As I continued to ponder to make that change I kept coming back just change the damn brake-pads and move on.

I have changed brake-pads on a bunch of cars over the years and Never-Ever has it turned out to be such an issue as this GT4.
And talking in person with the person that's suppose to know their business sometimes Sadly doesn't mean crap.
I'll go ahead and post a picture as an example of what I speak of.
And this guy/tech/salesman put me on hold and supposedly Double-Checked to make 100% sure these were an Exact Replacement Hawk Ceramic Pads (Replacements).
He came back on the phone and said, Terry I checked and these are Definitely what you want and the part numbers are correct your seeing.
Super nice fellow (Lee) but they are NOT the right size pads and I don't blame him at all he simply was repeating what he was told.



I'm still trying to purchase the darn pads at this point.
Hopefully I can get this accomplished while Porsche of Nashville still has the GT4.
So when we take delivery it will be 100% complete.
I personally don't like taking any vehicle to any dealership for any reason.
The less exposure to one's Porsche the better guys and trust me I do know as I worked for New Car Dealerships for over 16-years and I have seen what can and does sometimes happen to Customers vehicles.

Wait, so Hawk sells a part that isn't what it says it is?! I'm shocked!

Terry, I'd take this fitment issue as a sign from the Gods, saving you from putting **** pads on your very expensive sports car. If you do still go with these, remember, the first time you get in the car with the brakes totally cold, start braking 30 feet earlier than normal so the car stops in time. Even if just backing out of your driveway. Assume the brakes will do almost nothing on the first cold stop, work poorly on the second, and then by the third time you use the brakes they will actually stop the car. Not with any level of power or feel, but the car will stop reasonably close to what you would expect a car to do.

I got the hawk ceramic pads for my occasionally-tracked Focus ST, and I can tell you two things about them:

1. They require something like 2x the pressure to get the same stopping force compared to Ford's OEM pad for the ST (which had high metallic content, not organic).

2. They are completely unsuitable for track use even once.

Why not just use the OEM pads for the street? A proper brush, some soapy water and 20 minutes at the start of your wash will solve brake dust easily.

Personally I'd just stick with the OEM pads and then when they wear out consider a change if its really that bad, but not until then

As the largest seller of Porsche Race Pads on this website. I can tell you Hawk has many issues ( I quit selling them). THe most popular Porsche pads is Ferodo DS3.12.. FRont FCP4664G rear is CP4665G....they fit with no issues and perform wonderfully. Ask any users.
If you want to talk call me at 843- 299 0997. CLark I know what fits what an what people like and why.
