In my fervent search for information regarding Ferodo pads earlier this year, I've read the M2 posts and other people's testimonies, and as well as from my own experience - I can attest to the DS2500 being a great street, autox and light track day pad, and also wearing very quickly and losing Mu when being pushed harder or at higher temps.

I used to be VERY easy on the brakes when I first started tracking, but over time, as I demanded more and more, the DS2500 shortcomings became more and more apparent.

When I first installed a new set of DS2500 and bedded as best I could on public roads, they would very audibly squeal a moderate amount at lower speeds. It drove me nuts...but after a couple track days, that annoying squeal became a very brief and faint squeak at the end of a slow stop on the street.

DSUNO vs DS1.11 on the front with DS2500 rear is also an interesting thought for me. With 1.11 losing Mu with temp and UNO gaining Mu with temp.

I was advised you want a pad that gains Mu with temp for the fronts. But thinking about how DS2500 Mu changes with temp, perhaps a pad that loses Mu up front would match DS2500 better.

Even with aggressive rear pads R8 in my case the Fronts R10 and R12 were gone before my R8's were gone and that's with all the extra heat from ABS and the longer stops. That been said the DS2500 works amazingly well on the rear and besides the squeak that you noticed from them on the street they are amazing the current set on the car is very old set I had laying around in my garage and it's still wearing very modestly and I'm running slotted rotors. The DS1.11 is not available for my Brembo and 3.11 is only available if you alter it from a different shape. Which means the DSUno is the only Ferodo racing pad available for the S550 Brembo's. When I was running DS2500 on the front they were gone in a track day which was the reason I switched to Gloc based on the DSUno wear I think I will get a lot more track time out of them currently I have (58 laps on them) and they are more than 50% on 2 very brakes intensive tracks. For comparison the R10 fronts survived (134 laps).

I have looked for Ferodo pads online to fit my Dark Horse. Their dealer in the US is Essex
but they do not list any pads for my car.

They do show DS2500 and DS1-11 for the 2023 S550 with performance package.

Ferodo Racing shows them at 2015+ for the 15 inch (380mm) discs, which is the S550 performance package discs. The Dark Horse rotor is 390mm front and 355 mm rear.

The GT350 rotor is different, too.

It looks like Ferodo is out for the Dark Horse.

Here they are for the S550 but yeah overall very limited selection from Ferodo.

It seems like the S650 Dark Horse would be a target sort of market for Ferodo.

Does anyone know the part numbers for the Ferodo front and rear pads for the Mustang s550 GT PP1?

I found FCP4711W for DS1.11 Front pads. (H for DS2500 and Z for DSUNO).

I can't find the correct shape number for the rears. Looking to get DS2500 rear pads.

there is no DSUNO/DS1.11 rear pads. I run OEM rears (From Ford Dealer) they are essentially DS2500 without Ferodo branding.

Can you tell us how you figured that out?

I have been trying to figure out what the stock pads are on my Dark Horse for a long time now.

Yes I know I want DS2500 for the rear only. Would you by any chance have a part number for those of old packaging or something? The OEM rear pads from my dealer were not DS2500 I suppose because they faded very quickly and left deposits on the rotors.

For the front I want DS1.11 as those are supposed to last a bit longer than the DSUNO pads, have you tried both?

This thread actually talked me out of going with the XP12/10 combo. My main track is Zolder which is extremely heavy on brakes, I smoked my DBA Race pads which should have a temperature rating of 750c. Spa Francorchamps or Nordschleife I had no issues but don't go there as often.

I need a track pad that can handle heat and abuse because everytime I buy pads they get so hot that they glaze and leave deposits on the rotors and I have brake judder as a result. Have to throw them out even though there is plenty of material left on them.

Do you know how hot the rotors are getting? Use temperature-indicating paint to find out (I'm sure it's available from a race supply shop in your country). With that knowledge, you can use the temp.-friction charts many race brake companies have available to pick compound.

Do whatever you can to increase cooling to the rotors. Are you properly bedding in new pads & rotors?

You can knock the glaze off the rotors with 180-220 grit sandpaper or an aggressive Scotch-Brite pad. Use a dual-action sander if you have one. For the pads, lay a full sheet (approx. A4 paper size) of 180-220 grit sandpaper on a sheet of glass or very flat workbench, and move the pad around it in a figure-8 pattern keeping the pad dead flat. Clean both the rotor and pad with brake cleaner on a clean rag. Make sure to properly re-bed the pads & rotors.

bedded them per instructions. I have Vorshlag deflectors in the front for cooling. The first few sessions it was fine but the second trackday all I feel and hear is shuddering and the bite is gone. While they still stopped somewhat okay, I had to quit early because the vibrations got too severe and didn't want to damage any other component because of it (already had a broken wheelbearing) Tried sanding for an hour and rebedding but I think they are too far gone, were shining like a mirror.


I hope Ferodo DS1.11 can handle the heat better, it's really only one track where I have brake issues but it happens to be the one I visit the most.

Ford Europe use different part numbers than Ford USA. This is the part number I have for rear brake pads: 2310233 hope this works for you. I ordered DSUno because they have a bit higher Mu than DS1.11. My tracks are also very aggressive on brake pads but so far the DSUno life is good enough ( 96 laps on the pads). However my car has never stopped better. I'm going to Spa on 6th of September and the Brakes are what makes me nervous I will combine it with Nordschleife as well. I wonder how are this tracks on CHT temps as my engine is heaving troubles with temps.

Thanks for the part number. I might be there as well if the weather is good. I usually go early spring or late autumn so I didn't have much issues with CHT. I have an untuned ecoboost though so may be different, although the turbo does cause quite a lot of heat on its own. I have swapped the brakes with GT PP1 set, my car is a bit lighter maybe I can get away with the lower Mu of the DS1.11.

Is the center line of those pads quite big on one side? If so I'm looking at the correct pads.

My dealer has a price for this at something like a 360-70 Euro. The shape is the same but considering the price I guess this are aftermarket like OEM pads. My advice just order from the nearest Ford Dealership.

It's a track day multiple groups on 6th on Spa organized by the track we bought tickets months ago. So far the plan is to get to Nurburgring on Friday (04.09) Drive TF on Saturday (05.09), 4 sessions on Spa on Sunday (06.09) and do TF/GP track on Monday and Tuesday.

No these are the OEM pads, there is a picture of the packaging from Ford on the product page and is the same exact shape as my old pads I had. So yours have the big center gap too? Dealer pricing is also 70 so seems cheap. I'll try these out if you are saying that combo is good because when I ran the stock OEM pads they faded quickly and trashed my rotors with deposits, even in the rear.

They work great for me I need to buy a new OEM set but as I said my dealer have them at 370 which is a big difference than the 70 you have. If they are the same go for it. My rears are gone but overall my car almost don't use the rear brakes.
