Thanks for sharing, looks like your cables are longer than mine as mine would never be able to follow that path.
What 2-piece rotors are those?
EDIT: from what I see on yours, the cables go towards the front of the car however on mine, the EPB assembly is to the rear of the brakes, suspension, etc so my cables have to go in the opposite direction of yours, at least from what I can see.

those are indeed, same as the ones MaximA put on his car sourced from Spires.
Cameron, I have the Spires front rotors but mine have black anodized hats with Spires etched on them but I suspect you are correct based on your source. Glad to hear you are finally getting the car, not just because I need help with the cables but because I am intrigued by what you are going to do to it.

Picked mine up today, had a look underneath (but haven't had a chance to pull a wheel off) the cable is basically the same as what you see in the Spires pics.
I can see the handbrake electric motor, it's sitting kind of behind and above the diff. The cables loop forwards then go back towards the calipers. They are quite long, look even longer than the ones on the XJR.

Ordered the correct cables this morning and they should be here tomorrow, I did find a picture of one of them and they are quite a bit longer than the originals so they can do the S shape you described without the tension mine have now. Fingers crossed this is a simple exchange. Oh and the new GT/F-Type rack is getting installed this week.

The saga continues...
I ordered right and left cables, 2 different part numbers. The first set arrived from Jaguar with 2 different part numbers however the cables themselves were identical and the right side needs to be longer in order to reach and fit. So they sent me another set and year again the same problem. This time they requested a confirmation that the parts were unique to each side and different lengths. Third set arrived and again the exact same parts. So 3 of each part number and 6 identical parts and none fit the right side.
Am I missing something here?

jahummer,
The Alcon Performance Brake Package was introduced in the USA with the 2008 XKR Portfolio models and was standard equipment. For 2009, Alcons became a $5,000 option on the XKR Portfolio models. Alcons were not available on the 5.0L X150 models.
In addition to the obvious - calipers, pads, and discs - there are other differences between the standard brake system and the Alcon system. Among those differences are the caliper supports, flex hoses, brake booster, parking brake cable, etc. Those differences are apparent when you look at the replacement parts catalog.
You can compare the parts diagrams here: FRONT BRAKES for 2008 Jaguar XKR. There are several parts diagrams - scroll down to the diagram for Alcon brakes and with Portfolio. Make a note of the Alcon part # and compare it to same part for the 326mm brakes. If it's different, you'll need the Alcon-specific part. Note that this link is for the 2008 XKR, so it it's a Portfolio it has Alcons. That's not the case with the 2009, since not all Portfolio models had the optional Alcons.
Another thing I'm not sure about is if your Senta wheels will fit with the Alcons. My 2009 XKR Portfolio has Alcons, and the OEM Selena front 20x8.5 wheels have a +49mm offset and the rear 20x9.5 wheels have a +26mm offset. I don't know the offsets on the Sentas, but I suspect that they're different from the Selenas.
Also note the comment made by forum member u102768 in his post #5: https://www.jaguarforums.com/forum/x...iameter-85415/
"Brembo® and Alcon® calipers and discs provide higher-performance braking using the existing hydraulic braking system.
The brakes are installed to the vehicle using unique vertical links, hubs, hydraulic hoses and disc shields.
Due to the use of fixed calipers in place of the standard floating caliper, certain lateral dimensions on the vertical link and hub are critical to achieve correct clearance and operation of the brakes. Therefore special vertical links and hubs set within a certain tolerance are installed with high-performance brakes."
I hope this conversion project isn't more difficult that you thought. Good luck, and thanks in advance for keeping us updated with progress reports.

You're in the UK, so your 2008 XKR is equivalent to the US 2009 model year - the final model year of the 4.2L engine. The Alcon brake package was a $5,000 option on 2009 US models, so it's likely they were optional in the UK market, too. To be certain, contact Jaguar Customer Service.

That is quite a lot. The Dynamic Handling Pack on the 2009 US XKR sounds like better value:
Dynamic Handling Package (XKR) $8,000
Includes Alcon® performance brakes, revised road springs, revised
calibrations, 20-inch Takoba-style wheels
Dynamic Handling Package (XKR) $8,000
Includes Alcon® performance brakes, revised road springs, revised

And my Portfolio with factory Alcons most definitely does not have the XKR-S springs & shocks in it. Not yet anyway, they are sitting in a box on the shelf in my garage...

The fine print probably says "Specifications are subject to change without notice." As far as I know, every US 2009 XKR Portfolio model (4.2L) was equipped from the factory with 20" Selena wheels. Alcon brakes were optional in 2009, but standard on the 2008 Portfolios.
If anyone has a 2009 XKR Portfolio with OE Takoba wheels, let us know.
The 4.2L XKR-S was never sold in the USA. It was a one-year only, 2008 UK model equipped with Alcon brakes and 20" forged Vortex wheels. A fitting farewell to the 4.2L.

I have a VIN from a 4.2L XKR-S, which I used to buy the springs, shocks & tyre placard as spares (Jag won't release XKR-S parts without an XKR-S VIN) and funny enough that car is a 2009MY, B30xxx, actually a later build than my Portfolio and one of the last 4.2's before the facelift at B32753.
The build sheet for the XKR-S says SPORT TUNED SUSPENSION, the Portfolio is SUPERSPORT SUSPENSION
The SUPERSPORT SUSPENSION in my Portfolio is the green Bilsteins, same as any old XKR, the SPORT TUNED SUSPENSION is yellow Bilstein B6 shocks, with black Eibach springs that are a different p/n to the regular XKR springs. According to the tech guides, the XKR-S / SPORT TUNED SUSPENSION in the 4.2 is 10mm lower at the front and 15mm lower at the rear than the regular XKR.
The spec book does list "XK Dynamics Pack Option and XKR-S: 2009 up to 2010 MY" so it does exist in more than one document.
Interesting...

It appears to have been an option on the standard XKR so I wouldn't have though you would find a genuine portfolio with Takoba wheels.
