Aggressive offsets are always a bit hard to judge, as exactly how everything will fit will largely depend on the specifics of your exact setup- wheel pad height, true tire section width (advertised width is rarely exactly the actual width of the tire) your car's camber settings, etc...
You can fit a 19x9.5 +17 and a 19x10.5 +18, but you're going to have to be willing to adjust ride height, camber, and tire size to fit offsets like that.
Many thanks for the informative post. I'm going to have to talk to my wheel guy today. And come up with a plan, supposedly Volk recommends this for an "aggressive" offset. But I'm thinking I need to determine tire size first and then decide rim size.
