For anyone needing Alcon replacement front and/or rear rotors, I found a source thousands less than Jaguar. Apparently in 2008, Centric purchased a quantity of original rotors from Alcon. Jaguar has the fronts listed at around $1,000 each and the rears at around $300, centric has the fronts for around $130 each and the rears for around $100 each for a total savings of over $2,000.

 

For that price, you buy a set before they're gone, and throw them in a closet 'til you need them.

 

what are the part numbers - this is a centic supplier in Canada - but does not state whether they are Alcon..

Sorry, I should have included that info. The fronts are right 126.20025 and left 126.20026. The rears are right 126.20027 and left 126.20028. They have knock off aftermarket versions for about half that price, the part numbers are the same except the prefix is 226 instead of 126, but why even bother when you can get the real deal for just over $400 for all 4.

 

I'm showing prices of CAD $286.93 and $217.57 - but I don't see how we can tell these are Alcon made??

From the site:

StopTech 126.20028 - Premium Brake Rotor

StopTech Premium Brake Rotors are the best you can get for your performance wheels and tires.....

 

Unfortunately you cannot go by web info. They are not StopTech, they are from Centric. I spoke with their buyer after I purchased and received a rear set expecting StopTech and instead got Alcon rotors. Once they sell out there will be no more.

 

I'd be looking at casting marks real close. I've not got Alcons, so I'm a little uninformed there. But what is the vein design of known Alcons and the ones you have?
If they are straight vein, I wouldn't touch them.

Hi Vince

I assume you mean "vane". These are identical vane style to the ones sourced from Jaguar as I have verified this with Jaguar sourced rotors. The AP discs I have on the front are directional, neither the Jaguar branded rotors nor these replacements have directional vanes even though both have different right and left part numbers.

 

Thanks for the catch...
Gads it seems odd that Jag would sell a straight vane rotor for a grand.... They are by far the least expensive and poorest cooling option out there. (I had expected curved vanes at least.)
Ah well, as long as you got a high carbon casting, the price is fair for straight vanes.

jahummer,

$400 for all 4 Alcon rotors? If it seems too good to be true, it probably is.

Can you post pictures of those "Alcon" rotors, front and rear? If they're drilled with round holes, they're Centric replacements, and not genuine Alcon rotors. Alcons have crescent-shaped holes. If they're the "real deal" Alcons, please post a link to your vendor so I can buy a set before they're gone.



From Jaguar Merriam Parts website: https://www.jaguarmerriamparts.com/p...w=11&maxRow=10

I bought the rears from AutoAnything with free overnight shipping from Centric as I already had AP racing rings with Spires hats on the fronts. They are not Centric parts, they are not drilled. I spoke directly with the buyer at Centric and his story is entirely plausible. He said since Jaguar made so few XKRs with the Alcon package, it was not worth it to them to tool up for a custom rotor. He bought a quantity once in 2008 when they were made by the OEM supplier. As I mentioned previously they are identical to the Jaguar rotors, I have compared them to be certain, even the crescent slots are identical. There is only one detail that is different but shared with the R performance rotors as well has the Jaguar sourced Alcon rotors, the new ones do not have the word JAGUAR molded inside the vanes. I have no doubt this is because JAGUAR is trademarked, but the brakes themselves are not Jaguar, they are standard Alcon 6 & 4-pot monoblock calipers also fitted to other makes and models, so there is nothing exclusive or proprietary about the rotors.

But for comparison's sake, the first pic is a jaguar sourced rotor and the second pic is on my car. Keep in mind I painted my rotors so the vanes, hats & slots would not rust.

 

Thanks! They're the real deal at an unreal bargain price! I just ordered a set of 4, total cost delivered overnight for $466.16 (2 front@$132.99, 2 rear@$100.09) to put away as spares.

Saved over $1,700, when taking Jaguar dealer's prices plus sales tax into account.

 

I don't know if I mentioned it but this all happened by "accident". I was trying to source slotted rear rotors to match the front AP slotted 2-piece and was told by the sales rep the rotors I was ordering were Centric 8-slot and black E-coated. Needless to say I was very surprised to find Alcon rotors in the box, so I called Centric and explained everything to them which is how I was put in touch with their buyer and he told me the story.

The pricing is excellent and I would expect to pay about double that from Jaguar, not the ridiculously over inflated prices they list at.

 

I received all 4 rotors today and confirm that they appear to be identical to the OEM Alcon rotors on my XKR. They are much heavier than I expected, and the overnight shipping must have been very expensive.

My thanks again to jahummer for the heads-up on this real bargain.

 

Can you post pics of them please? I didn't and should have before I installed. Them. Thanks!

 

I have a 2013 XK Convertible. The autoanything website doesnt list the 2013 MY as an option. Does anyone know if these rotors would work on the 2013 XK? The car has the standard factory rotors. If possible, it looks like this would be an upgrade. Also, would any other parts need to be replaced/changed from the standard setup? Thanks

 

The Centric part numbers you are looking for are 125.20024 x 2 for the fronts and 125.20022 x 2 for the rears. I found both on AutoAnything with no issue. Looks like the total will be about $320 for all 4 corners with overnight shipping.

Unless you are asking about upgrading your brakes to an Alcon setup. I have done this on my XKR but only because I need brakes for track use. If you are not tracking your car the standard brakes are more than adequate.

 

Strange, I had to use the part#s you provided + Autoanything in a google search in order to find it for some reason. However it did come up and it looks like a great price.

I was considering making the change but i assume I would need to change the calipers and other parts which wouldnt be worth it for my non-track daily use. I think I will take your advice and keep with the standard brake setup.

Thanks!

 

I received all 4 rotors today and confirm that they appear to be identical to the OEM Alcon rotors on my XKR.
Pictured below are the right side, front and rear. I didn't take pictures of the left side, since they're virtually identical to the right side.

Just a question here... how much better are the Alcons than the stock 2010 XKR brakes? Mine has the "BRAKE UPGRADE PROGRAM", but the front rotors are 380mm compared to the 400mm Alcons with also the 6 pistons.
So, who has all this info? Is the stopping phenomenally better, or noticeable, quite a bit???
