I just picked up a 2003 Super V8. I've got some significant pulsing under braking, so I'm going to go ahead and do a pad change and either have rotors turned or replaced. Here's my question - does the Super V8 have the same brake set up as the XJR? Meaning I would be looking for 325mm rotors and pads for the XJR calipers?

 

depends on what you have, big brakes is not a standard fitment unless ordered that way. And yes replace the rotors, don't turn

 

My previous Super V/8 did not have Brembos

 

From what I can figure out on Wikipedia/Internet, the Brembos were only fitted to the R1 version of the XJR, and had the BBS Milan wheels to allow clearance for the Brembo calipers.

"Available on late XJR models was an "R1" performance option. This included 18" BBS wheels, larger Brembo brakes with cross-drilled rotors, and re-tuned suspension"

The supercharged engine was available in the "L" and VDP versions, but I'm not sure if that model came with the BBS Milan wheels/Brembo brakes, or even if they were available as an option. I can find plenty of pictures of XJRs with BBS wheels, but no "L" or VDP examples so equipped.
Anyone out there have any more info on this?

"The Daimler and Vanden Plas cars were also available with the supercharged engine otherwise found only in the XJR. This model was named the Daimler Super V8. In the US market, this combination was available only as a special order though 2001 (with these cars identifiable by their "Vanden Plas Supercharged" rear badging). For US model years 2002 and 2003, the equivalent Super V8 model was then offered. These supercharged long-wheelbase variants were also fitted with Jaguar's proprietary "Computer Active Technology System" (CATS) adaptive suspension.[15] The "Sports" setup from the XJR application, however, is replaced by a "touring" set-up, exclusive to supercharged Daimler and Vanden Plas variants.[16] It is softer and more compliant than the XJR's Computer Adaptive Technology Suspension system".[15]

 

So "base" XJRs had 305mm brakes and the 325mm size is the Bremen option on the R1 package? If so, I'm fairly certain I do not have the big brakes. It is riding on a 17 inch wheel.

 

These are the BBS wheels used with the Brembo brakes..................

 

early XJR's 1998 had 305mm. Late 1998/early 1999 jaguar moved to 325mm for the XJR's (not sure if NA fallowed suit or not). The brembos are 355mm front & 330mm rear + BBS wheels

 

 

Because a definite answer about front brake rotor size in the Super V8 is very hard to find: The 325mm ones are the correct size. no more, no less
I measured them myself at my '99 Super V8.

(sorry, the topic is not new, but the correct answer was still missing)

 

Thanks for the confirmation regarding S-V8 front rotor size. I learned the hard way not to trust online distributors as they all state the 355 mm rotors are what is one the 03 super V8. That is what I ordered and upon removing the wheel found it is 325 mm. I now have ship the rotors and pads back on my dime with a 10% restock fee. I kick myself for not measuring prior to ordering. Live and learn.
