I am looking for the correct size replacement rotor my '99 XJR. I am finding conflicting sizing and I am wondering if anyone knows the diameter of the rotor? I'm thinking it is 325mm, but each site I go to seems to give me different results when looking for the correct rotor. When I bought the car, the previous owner gave me the pads and rotors he purchased that he hadn't yet put on... I've got the calipers off and am trying to free the rotor, when I noticed that mine original is bigger!

Also, any recommendations for rotor brands so I don't get any of the cheap chinese junk?

 

I found that the size is definately the 325mm and I see some places refer to them as 12.8".

Now, does anyone have recommendations for rotors. I'm just looking for an oem replacement of excellent quality.

 

Brembo replacement rotors are usually top-notch.
