In an effort with Essex Parts we finally convinced Ferodo to offer both DS1.11 and DS2500 for the 991S. Pads will begin to ship on October 6.
If you want the best option to Pagid RS29 try DS1.11 and see why all that use it don't go back to either Pagid or PFC.
FRont pads are https://apexperformance.net/product/fcp-4955w-ds1-11/ and https://apexperformance.net/product/fcp-4955h-ds2500/

Rear pads are https://apexperformance.net/?s=4713&post_type=product

The Fat Kid

What is the difference between the two? How is the dust compared to RS29s?

I don't mind the squeal of the Pagids, but the dust seems to turn into a sludge when washing the wheels. My wheel have a ceramic coating, and OEM dust came right off.

Clark-ApexPerformance

Numerous customers have told us that they feel the dust from the DS1.11 is
much less than the competitors.
The performance of the DS1.11 is much superior to the RS29. THe modulation is to die for. This DS1.11 pad is the current favorite of GT4 and 991 GT3 track junkies. Many tell us it feels like you don't have to push the pedal as hard to stop the car.
Unlike the RS29 the DS1.11 is good to the backing plate. Many tell me once you get to 1/2 a pad the RS 29 stop working.

Do you have any options for the base model 991.2?

smbryan

wow those are some expensive $ brake pads

The DS1.1 is a pure track pad and not recommended by Ferodo for road use (you have to get heat into them before they will be effective).

Both the RS29 and DS2500 are great cross over pads

Clark-ApexPerformance

Both RS29 and DS1.11 are track pads. DS2500 is a cross over. Although Ferodo doesn't recommend running DS1.11 on the street many of my customers do with no ill effects.

I've been using RS29's on my 991S for track use for several years and have no real complaints. But the new Ferodos interest me. You mention better modulation, but does the pad still feel firm/solid when heated up? And how would you compare the longevity as a track pad when placed side by side with the Pagid? Also, can the Pagids and Ferodos be mixed? (I need rear pads now but have some life in my front Pagids. Hate to throw $$$ away! )

Clark-ApexPerformance

Customers who have used RS29 previously have told me that the Ferodo DS1.11 lasts longer and stops the car better. Their is no fade with the DS1.11
You can use RS29 up front and DS1.11 in the rear. The front is what is stopping the car.....the rear is along for the ride. As long as you don't put a pad in the rear with a ton more initial bite, you are good to go.
Have had some customers switch to the Giro Disc front rotors that allow you to run a GT3 pad up front. They have been using DS1.11 up front and RS 29 in the rear.
Up until now RS 29 was only decent pad choice you had for 991 S/GTS

The RS29 is slightly more aggressive than DS2500 and keeps its bite a little better at higher T

RS29 cf 0.4 - 0.44 from <100 to 700 degrees C
DS2500 cf 0.38 - 0.43 from <100 to 700 degrees C

The best cross over pad I have used is the Project Mu street sport HC800 cf 0.38 to 0.62 and operating range of 0 to 800 degrees C

Honestly, I would never use DS1.11 on the road - cold winter mornings - T junctions and intersections do not mix. If you had an incident, at least over here, you would be in deep pooh. Insurance wouldn't be paid out and if somebody was hurt you would be in very, very deep pooh. Just because you can doesn't mean you should

Personally I wouldn't mix pads with different coefficients of friction as it alters the brake bias e.g higher cf pads at the rear will move the bias rearward. This may lead to some unintended consequences on a car with plenty of rear weight bias.

Clark-ApexPerformance

Your point about weather is well taken........customers here using them on the street don't encounter "cold snowy" conditions. You need to move to a warmer climate.
Have at least 6 guys running with DS1.11 up front and RS29 in the rear and they love it.

randr

Ok that makes more sense as it will add more front bias. We used to do that with our V8 Super cars (RWD) helped with high speed trail braking e.g. less chance of losing the back through inadvertent lock up.

Clark is this true of all GT3 pads? Have PFC produced a 991.1S pad? Endless? TNA

LTP

I assume they make loud squeaky noise since for track use?

Clark-ApexPerformance

PFC has no pads for the 991S...go figure. The only option I am aware of is RS29 or now DS1.11 or DS2500 from Ferodo.
You can use the GT3 pad on any 991 S with the coresponding Giro Disc front rotors. The front calipers on the 991S are the same as the GT3. Porsche for reasons unknown made the hat larger on the 991S so the standard GT3 pad will not properly seat......Giro Disc fixed this by making size of the hat smaller.
