Did the front brakes change in 1997?
I've been shopping for some new rotors for my 1997 XJR, and noticed that the front rotors for that model year XJR are a bit harder to find than an XJ6 of the same year, or front rotors from a 1995 or 1996.
In fact, NAPA doesn't even carry a front rotor for a 1997 XJR at all.
Checking front brake rotor part numbers at Carquest (for example):
1997 xj-6 Part Number: 34183
1997 XJR Part Number : 34322
1996 xj-6 Part Number : 34053
1996 xjr Part Number : 34053
1995 xj-6 Part Number : 34053
1995 xjr Part Number : 34053
So clearly something changed in 1997 with the front brakes. Any idea?

No clarification on if the 1997 XJR front brakes use a larger rotor than 95/96?
Some auto supply houses show the smaller brakes as appropriate, while most show the "one year only" larger brakes.
Hate to order the wrong part. Also just curious if this was a performance upgrade in 97 that went unpublicized.
