imho rethink your wheels and get the Bilstein, a set of light 17x9 square with +35 offset will clear stock suspension, and the Bilstein springs actually taper down to a narrow id at the bottom (I think even up to +45 clears stock, it's just super tight, and with big tires it'll get tighter, but you can space those out and extended studs because racecar, +40 might be perfect with a 3mm spacer up front). Some high quality 255-265 tires will give you as much grip as your proposed setup. They'll be cheaper than 19" tires too.
Another option is putting linear rate springs in the Bilstein, more expensive than off the shelf but local support should be able to help and you'll get as much clearance as the other options.
I'm not dissing the rest of your coilover options, it just stuck out to me that Bilstein is kind of your first choice and the things holding you back are poor choices for what you want to use the car for (street, aggressive driving, slim chance of track use) as staggered 19" wheels on this car are just for show giving you reduced handling capabilities and potentially very poor ride quality. I'm sure some people love that kind of setup, and hey, maybe it is exactly what you want and the tradeoffs aren't noticeable to you and are totally worth it.
Best of luck.
