Regarding the mixed set (RE71R/Yoko), I ran the 285/30-18 Stones front with 295/30-18 Yoko rears at Nat's in my M3. It was magic, my driving less so. Ido W. (owner of the winning car) took it for a run on the practice course and was grinning ear to ear. They immediately changed plans and ran the Yoks. At least one top tier BS competitor who can identify himself here also tested this setup for his M2, and agree this was the setup. Foley and Emmert mounted 295F/315R Yoks on their 1M wheels which seems crazy. I suppose if you can get the 295's on front, I'd go that square.

I ran the mixed set because I previously ran at the Peru tour the 265/295 Yoks and hated how bad the front of the car was but loved the grip in the rear. Car would just not take a set. On the practice course, a spent set of 275 Stones paired with the 295 Yok's was .3 faster on a 32 second course...first run. Drove back from Peru, thought about what would work with the 295 rear Yoks and settled on the 285/30 Stones. For anyone so inclined, mounting the 285 Stones on a 9" wheel can be a total PITA.
