Found a Uk site that does grooved and slotted rotors and different types of pads. My car came with rear slotted and grooved rotors, so want to replace with the same. I want to match the fronts also.
There is 5 types of disc, which would you choose.
Which pads would you choose.

I see theres 2 front sizes, i think mine are the 355mm.

Brake Discs and Pads for XKR 4.2 Supercharged 06/06-06/09

 

Powerhouse - I would go with ceramics - a little softer, but no dust to speak of, here in the states lots of people recommend Akebono. I had Centric on my 12 XK. Have not needed new pads yet on the XKR.

 

I second the Akebonos. Have them on Mercedes and Jag.

 

Ordering the disc before the weekend, can someone just confirm that these discs are the right size for my 2007 xkr standard brakes:

FRONT DISC SIZE: Vented Diameter: 355.0 Thickness: 32.0 Minimum Thickness: 30.0 Height: 48.2 Bore Diameter: 71.0 Studs: 5

REAR DISC SIZE: Vented - Diameter: 326 Thickness: 20 Minimum Thickness: 18 Height: 38 Bore Diameter: 64.5 Studs: 5

Found this sit doing black diamond discs, are they better
