I just spent $700 just on the front rotors. It's an R1 XJR and I heard they automatically came with Brembo brakes. It had drilled rotors when I bought it so I got drilled rotors again. Could I have gotten regular rotors? I don't do the installing but I was only charged for 2 hours labor. I heard Jaguar charges $900 just for the rotors.

 

Depending on the size possible? I purchased a set of Brembo rotors for my 1999 XJR and drilled them myself, these were not the large (355mm?) I probably should have left them alone but I was doing mild track work (enthusiastically) and after about 2 seperate sessions over a period of a month one of them cracked luckily not on track.

 

try a set from britishparts.co.uk...ebc are fine as well...I've used them for years

Installing The rotors can be done in minutes. Its just 2 bolts. Pads on Brembos are even easier than normal brakes.

The drilling is more because it looks cool rather than any functional purpose. Most track oriented cars with factory Brembos (other makes) use undrilled rotors because of cracking concerns.

 

well this pretty much says different :-/ from a brembo executive him self .

Relative .... in a track situation the rotors are always working at the limits .. this is not the case with passenger cars. A well designed system (large enough for the mass of the car) in a passenger car will have few times (if ever) where the extra cooling is required.

 

My car has OE-fitted Brembos (they're 365mm front). No need for drilled for normal use.

 

I have the same brakes as jagv8 and just last weekend overheated them with quite bad brake fade with what I'd call normal firm road driving .and that is not the first time it's happened . our roads at steep and twisty by nature (also very fun) , and hard on brakes ,
but the point is the holes are not just for looks ,
I see this posted a lot and it's not true , cross drilling does have a reason other than appearance.
And if you require upgrades from standard brakes there are options .
Including cross drilled and or slotted rotors . I will be going this direction
In the future as I can easerly find the stock brembos limits.
It really depends on the conditions and driver wether or not to up grade .
I can think of at least two old treads stating the STR brembos were fading with in 3 laps of a track day , 3 laps of a genral sized track is far from as far as I want my brakes to perform , even for fast road use .
BTW most brake tech is handed down from track to road application for good reason , most high end Porsche's Audi's and farraris and BMW's have cross drilled brake rotors stock . Or extreme next leval is Carbon .
if your not overheating your stock jag brakes then stick with that tech .
But there are advantages to cross drilled there is no argument !

 

If you're reaching the limits of your brakes then you should be looking at better pads first.
Thinking that a few holes in your disks are going to help cool things down is like using a band aid on a severed limb.
Having seen first hand how cross-drilled rotors can crack around the holes, I am staying well away from them for my Brembo upgrade. Slots and dimples are more than enough to keep the pads clean.

 

From the Article:

If there is enough water to impede the brake pads from working properly without holes in the discs, don't drive your Jag, because there is also enough water to destroy the totally un-sealed front wheel bearings.

 

I knew I should've checked before opening my big mouth!
Just checked the Brembo disks I ordered from SNG Barratt, and they're drilled
Needless to say, I will be keeping a very close eye on them, especially if I ever get it to the track. For road use however, they should be completely fine, and I have a little more confidence in them as I have stuck with genuine, rather than an aftermarket replica

 

Drilled looks way cooler. I put drilled/slotted on everything, to impress my kid and his friends.

If they crack, I'll buy more. Coolness isn't free.
