Factory Diameter setup's are 325/30/19R & 275/35/19F ,The Michelin PSS tires are probably some of the widest tread ones.
"Rusty" has that Bad-Azz look!!!
i was thinking Pro-Street look 345/30/19R & 255/40/19F MPSS on 8.5 & 12" Forgelines.
or 295/35/19F on 10"wide wheel.
PS...."Rusty" also has unlimited funds!

You are spot on. the 285/30r19 FR and 335/25r20 RR setup is with PSS ZPs (run flats) same as the C7 vettes. I am not keen on the idea of run flats, but you can't argue with the handling success of the vettes.
Last night after spending some time with tire calculators and searching TireRack I also came across an alternative 275/35r19 FR | 305/30r20 on regular PSSs that would work better (2.2% diff FR>RR) and also fill the fender wells more (i.e. larger diameter than the wider ZPs mentioned). This option wouldn't create any problems with the TCS, but I lose width in the rear. It also has the advantage of being the same width as RS3 tires I will run as track tires.
So the 275/305 setup is currently my top choice if i decide to go 19/20. I expect the narrower rear tire won't have a major impact on traction. So, the only thing I lose is my spot in the "370z Wide Tire Hall of Fame", next to Rusty.
