Have an XFRS but had XFR in the past.
Performance shop telling me they can't find drilled (no slots) rotors for XFRS but can find them for XFR.
I think they are the same it is just that XFRS is rare and not in some companies database.
Are they the same rotor size and interchangeable?

 

Yes, the XFRS has the exact same brakes as the XFR, 380 mm front twin piston and 376 mm rear single piston.

 

What Oz said.
Looks like the rotor fits many models...

Yep, again the 380 mm and 376 mm rotors are identical across a wide range of Jags - XFR, XKR, XJR and F-Type to name a few.
I have direct experience with them on my F-Type, I swapped over the front rotors from my old XFR then a few years later I upgraded the rear brakes from 326 mm to 376 mm using the "old" rotors from the XFR.

 

Thanks. What I thought, just wanted to verify.
