2" drop and 17's?

ive got an '03 civic si and i was thinking of getting the h&r sport springs with koni yellows. im a little worried about the 2" drop though. i was also thinking about the ground control coilovers with the koni yellows,but im not sure what the drop range is with that setup. i have 15" stock wheels now, but ill most likely end up with 17's, probably next summer. im just wondering if a 2" drop would be ok for daily driving. i dont really want to have to worry about rubbing my tires on the wheel well everytime i turn. also if anyone knows the drop range of the gc's ide appreciate it. thanks alot.
