Hi folks, I have recently undertaken to install 05 xjr Brembo brakes on my 97 xk8.
I had to have brackets made to accept the much larger calipers. However the 12” existing rotors swap out perfectly with the 05 xjr 14” rotors.
I have about 500 mi on them now They are a vast improvement over the old setup. They stop smooth with no chatter of any sort.
I just ordered the rotors for the rear, so will keep you all posted.

I also had to have special brake lines made locally. Cheaper than factory lines.

Be aware that some kits that are offered use the smaller rear brake calipers in the front.
I could not find any kit that used the large front calipers. They are a tight fit.!!

 

Corry, tell us what getting them made entails when you get a chance. I can't imagine what was involved, the complexity, or how you chose material for such a critical component.

Thanks, John

 

I's really like some more detail on how and what problems you encountered as I have a full set of Brembos off a 2004 XJR that I'd love to install on my '99 XK8. I originally bought them to put on my wife's '04 XJ8 but the electric rear parking brake added more problems than I wanted to deal with so I just stored them.

I'd love to put them to use in my XK8 if it isn't a ball buster to do.

What about wheel size? Did you have to swap to a bigger set? What about front suspension clearances due to the bigger calipers and rotors? That kind of thing.

 

To start with I am a retired Mechanical Engineer. With access to a metal fab shop.
The caliper anchors to the lower lug. The adapter plate has 3 holes in it. I had made extras, but my local Jag shop bought them from me , before a thought about taking a picture of them.
I will have some more made if there is enough interest.
You will need 19” wheels. I have 20” wheels because they came with the car. I would recommend 19 in.
I trimmed the dust shield with aviation snips.
The suspension clearance is tight, about 1/8 in. Have had no noise and no contact.
I found that pre fitting the setup, before installing the new rotor gives you lots of room to work. This will give you an idea how it all goes together.
I can have more braided brake lines made up as well. The guy I used happened to be a British mechanic. So was happy to help. I spoke with race car builders on the type and thickness of the steel required. South Florida is full of speed and race shops.

 

You can use some 18" wheels with no problems. I have the Whitleys and they work perfectly. Originally I had 18" Double Fives and they needed spacers to fit.

 

Hello, I have a 1999 restored XK8 that I would like to fit som Brembo from a 06. If possible I would love to purchase the brackets you made for the larger front rotors. If you are able to assist in any way I Please let me know?

 

Did you use the hard to get XKR Silverstone front Brembo Calipers, or the more common S-Type / XJR Brembo calipers with the uneven mounting flange holes?

 

Thanks for the replying. I bought a full set of red 2006 victory edition XKR Brembo’s. Hopefully, I can find a way to get them on my restored 1999 XK8.


I would very much appreciate any ideas or sources for adaptors!

Thanks
Jeff

Jrand, I’m going to HIGHLY recommend that you upgrade the front knuckles to a 99’+ XK assembly. They have 4mm larger wheel bearings and will last considerably longer than the already too small for a stock car. If your putting the Brembos on and larger wheels, you really need to upgrade to the larger wheel bearings. Just food for thought.
