There's not a lot out there, but here's a couple.
ExtremeContact DWS 275/45ZR19 = 28.7" diameter
Eagle F1 Supercar 315/40ZR19 = 28.9" diameter
Tire sizes available by wheel diameter (Tire Rack):

I'm looking at MPSS with M350s for my '14 GT (Track Pkg).
Leaning towards M350 19x10 & 19x11 with MPSS 265/40R19 & 295/35R19 (stock BMW M5 & M6 tire setup). These highly rated tires are relatively light and the wheels are expected to be light as well. Unsprung weight is your enemy.
Won't...
I've been considering the MPSS for a while in a 19" staggered size. Now with the M350 about to be available in 10" and 11" widths it's all coming together.
305/35ZR19 are now available in the Michelin Pilot Super Sport:
