If you opt for a 10.5" wide wheel over an 11" wide wheel you can use a slightly more aggressive offset, but your ultimate position of the outside of the wheel relative to the rear quarter panel will remain the same, as there is only so much space between your car's hub and the quarter panel.
Sadly a bolt-on fitment and a truly aggressive fitment are opposing factors, with the more aggressive fitments being less "bolt on", and the more "bolt on" fitments having a less aggressive look. The closer you get to an extremely flush fitment, the more variables like variation in tire carcass size, your particular car's camber settings, etc... will nearly guarantee a need for some adjustment once the wheels are actually on the car.
The 9.5 +22/11 +30 sizes I am suggesting are a safer bet than the sizes you were recommended initially, but both will work. The sizes you posted in your original post are very aggressive and will look great, but will need a bit of adjustment before the wheels fit correctly on your car. The sizes I am suggesting are more likely to need little to no adjustment to work.
