1. The stock size for 83urq is 205/60-15 on 15x6x35 Ronal R8s.
2. The Bentley has a mistake and says 15x8x45,it is actually 24
3. The 15x8x24 Ronals were optional on the 84urq, std on the 85urq
4. With the 15x8, the stock size was 215/50-15
5. The cars that came with 15x8 had factory rolled fender lips
6. ET34 is more pushed in than ET24, so it would be LESS likely to rub
   on the fender lip, more likely to rub inside, like on the control arms

Several other listers, and non lister urq owners run the same sizes I do:
  225/45-16 on BBS/RF 16x8x34 for street
  225/50-15 on Ronal 15x8x24 for track

I also have the H&R lowering spings, but Koni adjustables, and I rolled my
inside fender lips myself. Compared to a factory job, I have only
rolled them maybe 70% of the way. My observations:

With the BBS/RF in street driving, no rubbing whatsoever.
With the BBS/RF at NHIS, at the diving right turn 10, I get a small BEEP
  I have traced this to the inside sidewall of the LF tire hitting
  the control arm bushing, no big deal at all.
With the 15x8 on track, I regularly polish about 1 inch of the rear
  tire sidewalls, I guess I should roll the edge some more.

I hope this helps
