My car been a 2007 xkr, can anyone tell me the size of my Rear and Front brake discs. The rears are of drilled holes and slots design and need replacing as i am doing the pads as well. Fronts discs are flat, but want to replace them with those of the rear design.
Found these on the MTEC BRAKES site, what you think,

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

there is 2 front and 2 rear sizes, but i don't know which is my size as i would have to have them out to get the size.
Then there's the pads do i go for Mintex, then there's , Red, Yellow and Green stuff, what's the difference.

Does this video explain it as it is or anyone disagree,


Any recommendations most appreciated.

 

The information below is from my workshop manual. I don't think your Jag had drilled and slotted discs on it from the factory. Mine didn't and I haven't seen one that had them unless I already knew they had been changed out.
