That's already been answered several times: No. No one has because from a performance stand-point it's not necessary.

If webtech was still free you could research it all day/night. The only other option is to spend a day at the junkyard and figure it out. Even then its not going to be 11", its going to be 10 or less because none of the potential matches use an 11 in the rear. OR, as I stated before, invest in a legit BBK.

 

I can understand everything now...so I will keep my stock rotors and calipers for rear.

 

I believe the Tib could definitely use a bbk up front. It didnt like stopping from 80mph. I noticed a nice improvement after the XG swap. A rear bbk is unnecessary but would definitely look much better.

 

I'm back!

Following JonGTR, I would prehaps have in mind to install my SPECTRA5 rotors for rear... but I don't know the distance between the 2 holes to install the rear calipers of SPECTRA5, so that I will compare with the distance for RD2 ? Can someone help?
