I have 2012 XKR-S and I need to replace my rear brake pads. According to several dealers the correct part number for my car is C2P25493 and it should look like this
However, when I look at my old pads installed, they look like C2D3792
The main difference here is the anti-rattle spring that attaches to the top of the inner pad for C2D3792 and all the springs attached to the back of the inner pad for C2P25493.
I am not the original owner, but I bought the car when it was 1 year old with 1,500 miles (it has 20,000 now) from a dealer and it's likely that pads installed are the original ones from the factory. However, if that's the case, why it's a different part number / design now?
Can anyone with XKR-S comment here? What do you have in the rear? Do you have to anti-rattle spring installed on top of the inner pad? You can see or feel it with your finger even with the wheels installed. That's the easiest way to tell them apart. I am really puzzled as why I have C2D3792 installed and the dealer says I should have C2P25493
BTW, if I go directly to Ate site (brake manufacture) and look at their recommendation for XKR-S, it's C2D3792 (what I have installed) as well.

Use the old springs. Done.
I do believe my non-S also has these springs and I sort of remember using the old springs on new pads a few years ago. Not positive, as I'm old and mentally feeble.
I did my 2014 XKR Dynamic-R during the winter 2019-20 and the dealer ordered the wrong pads based on my VIN. The correct pads were listed for around much more. My car only had 15,000 miles and never had breaks touched before. The pads on my car look like the first image, C2P25493. The dealer wanted an arm/leg for the correct pads so I ordered a set from Rock Auto which work great and look exactly the same as the originals.

Do you remember by any chance what you ordered from RockAuto. I checked them and I see nothing available that looks like the first image.
First pads are around $430 from a dealer and second ones are much cheaper at ~$120.
I don't have an XKR let alone an XKR-S but I did have a 2010 XFR and I now have a 2014 F-Type.
Both have the same 376 mm rear brakes as the XKR-S but with very different pads.
The XFR pads looked the same and were possibly identical to the C2D3792 and not like the C2P25493.
The "anti-rattle" spring you talk about on the pictured C2D3972 is not an anti-rattle spring at all, rather it is the brake pad wear sensor clip.
On my XFR with the same pads the anti-rattle spring was attached to the outside of the caliper, not the pad. The F-Type is different with little springs attached to each end of the pad. Neither are anything like the pictured C2P25493.
Point is if the existing/old pads look like the pictured C2D3792 you should have the external anti-rattle clips as well, and if you do you want the C2D3792 not the C2P25493.
I ordered 2 different sets from RockAuto. I believe I used the first ones in the picture. The spring on the back of the pads is the anti raddle spring which slides onto the caliper. The wear sensor fits into the wedge on top.

I've merged your two identical threads on this topic posted 7 minutes apart. It looks like you tried to include images but they didn't upload?

If you look closely, both pads are actually the same ATE items. The XKR-S version has the extra backing plate pressure springs but they fit in the same calipers common to all these 5.0 S/C cars. Those backing plate springs are amazingly expensive!!! It is possible that the springs help with pedal feel or reduce knock-back effects, I don't know. However, if you want a 100% stock XKR-S, the C2P25493 are the correct pads. If you are OK with not having the extra springs, the C2D3792 are the same pad with the same friction compound (DOT edge code FF). Maybe later XKR-S didn't have the C2P25493 pads or yours left the factory with the less fancy ones. Either way it isn't a big deal.
In the UK, the base ATE-labeled version of the C2D3792 pad (13.0460-7255.2) can be had for 50 Pounds or less. The Jaguar-boxed C2D3792 lists at 130 Pounds. The C2P25493 lists at 420 Pounds but can found at around 200. Keeping it original is expensive for a rear pad that doesn't make much of a performance difference.
Mintex does an affordable copy of the C2P25493; the MDB3707 but it seems to have a less good compound (FE).
EDIT: I just noticed the issue with the wear sensor fit. It looks to me like the C2P25493 pads take a sensor like the one for the front - simple push fit into the existing slot. The C2D3792 has a different ant-rattle spring that slots into the same recess and the wear sensor slots into the "O" in that anit-rattle spring. The C2P25493 comes with a wear sensor to suit supporting the theory that they are different (C2P24219 instead of C2D2976)

Thanks. It looks like my car left the factory with C2D3792 and old style wear sensor. It appears that starting from 2013 Jag started using C2P25493 with a new sensor that fits. This would explain why many part websites list C2D3792 as the right part from my car and not C2P25493. Jaguar is the only one that claims C2P25493 as the correct part number. The only change appears to be the backing plate and new wear sensor.
Do you know if any of them are FF? I saw that Pagid is FE from a picture. Have not investigated the rest yet.
Nope All the photos I found suggested that they are all FE-rated. So far, the only FF rated pad I have seen are the ATE ones. Ferodo do a GG rated one but with the standard spring clips and not the "on-piston-locating" clips. I'm tempted to try the Ferodo ones just out of curiosity.

Do you have a reference number for a Ferodo pad? My current pads do not have "on-piston" clips.
This comment is the result of my searching for the correct porterfield pads for my 2012 XKR and ending with more questions than answers.
Porterfield offers 2 rear pad part numbers;
2010-2012 = AP1449 (with spring)
2013-2015 = AP1747 (no springs at all, different sensor cutout)
Why would they separate 2010-2012 and 2013-2015?
After seeing this thread, and the different spring designs, I became curious to see if the XKR-S part number pads would fit on my XKR...
Is there any advantage to one spring design over the others?
Are there compatibility issues between the multi spring XKR-S pads and my calipers?
Do any porterfield pads have the springs on the back?
I have red calipers, but am not sure about the part number (VIN B46623)... I only found one part number for red calipers, so it's a good possibility I have C2D39490/92.
As stated in the first post, there's at least 2 options of pads (possibly 3); one with angled sides and a single spring in the wear sensor cutout, one with flat sides and a single spring, and one with flat sides and multiple springs on the back of the pad plate.
Sorry for the late reply. Been a bit overloaded in other areas lately.
Did you get to the bottom of your searches for alternatives?
The C2D3792 and the C2P25493 pads appear to be identical pads (identical markings, codes etc on the back) with the C2P25493 having the added XKR-S mountings and either type should fit the 5.0 XKR calipers. The C2P26112 should not fit. I have heard that people have used the C2P25493 pads on normal XKRs and report slightly better braking! How the extra mountings springs work, I have no idea but maybe they provide a little more feel. The pad is the same so the actual braking should be pretty much the same.
I did try the higher friction Ferodos and notice that smooth gentle stops are easier without any/as much creaking from the front. A surprising change but it really seems to be there. I'm very happy with the combination of OEM/Jurid front pads partnered with the Ferodo rears.
Nope, never got a straight answer... That does help, though. I'm still not sure why porterfield doesn't offer any pad with the XKR-S spring style, or which of the two different styles of cutout for wear sensors will fit the cables on my 2012 (if not both?).
