ANvaros100, the XJ has 2 styles of brakes. You have the standard brakes that come on the 3.0L and naturally aspirated 5.0L engines. All the supercharge 5.0L engines have the upgraded brakes (ie, are 1"/25mm bigger in diameter). So, you need to know what you have first. if you are looking to install the supercharged 5.0L brakes on the other style, you can do this but you need to change a bit more than just the calipers. There are some write ups here that will help guide you to what is needed to make the change.

Look before you leap. Sure, aftermarket drilled and slotted brakes look cool. But why doesn't Jaguar offer them from the factory for the XJ? Jaguar makes high performance street vehicles and, with all other things being equal, drilled and slotted rotors will reduce performance. Holes and slots reduce the surface area of the rotor, which reduces the swept area of the brake pads. Less swept area means less friction and less stopping power, and longer stopping distances.

For racing applications, cast iron drilled and slotted rotors provide better cooling than OEM solid vented rotors but are usually larger (and heavier) to make up for the loss of swept area. For street applications, solid rotors stop better, are quieter, smoother, and last longer.

My 2009 XKR has the rare $5,000 optional Alcon Performance Brake Package. Front rotors are 400mm with crescent-shaped grooves and 6-piston Brembo calipers. Rears are 350mm with crescent-shaped grooves and 4-piston Brembo calipers. Here's the front:

I installed R1 Concepts ELine drilled rotors and Hella-Pagid Semi Metallic Pads on my XJ with the big 380mm brakes. Very happy with them.

I don't think there are any aftermarket calipers for our cars yet, but I may be wrong.

Why do you want to replace the brakes? Seems like a pointless waste of money. Why not get a Honda to modify instead? Aftermarket parts are readily available for them.

Anvaros100,
You haven't told us why you want to change the factory brakes. For looks? For shorter stopping distances? How is the cost worth the benefit? What's wrong with the factory brakes?

looks and distance. What else it could be? And why are u so interested in this. Factory brakes works bad if many times from >200kmh at short period Can’t work more then (sorry for English) and I wrote above that they looks like from polo. Before used only amg, that brakes looks like they should look on power car

See this thread:
https://www.jaguarforums.com/forum/x...rilled-139577/

Your Public Profile shows that you have a 2010 XJL 5.OL Supercharged. I don't know if these companies ship to Russia, but they offer several aftermarket performance brake kits and pads for your car.

Good luck!
