Those wheels were specifically designed to be used on the exact car you plan to mount them on. The tires sizes you indicate are very near perfect for the car. Now provided you don't plan to add spacers to the install they should fit under the fenders like they were intended to. The Steeda Progressive springs are conservative in the amount of drop and unlikely to cause any issues provided you get an alignment after install and you clock the bushings.
You don't have anything to worry about if you don't count all the folks asking you about the wheels and tires. They and I will be jealous.
Oh and be sure to post some before and after pics right here!!!
