Dammit! We just HAD this conversation. Still not enough info though. Define "aggressive stance". State your budget. Help us help you.
You say that the stock dampers need to be disassembled and the Koni dampers inserted? We aren't talking about inserts here they are actual dampers that the GC coils sit on, It's not much work at all.
Don't forget too that the GC coils have a lifetime warranty as well.

$1100 sounds a little high, like with four tophats which most people dont need unless really slammed. The cheapest price ive found for GC/Koni is from NoLimitMotorsports for $825 total with free shippping and no taxes.
If you are going to be daily driving this car AND want an aggressive stance, you are gonna need some high spring rates to keep from bottoming out or rubbing. Given how hard it is to pinpoint exactly what you'd need because everyone's driving style is different, you'd be best off with an adjustable setup.
If you're not that mechanically savvy and just want something cheap to buy and throw in for looks, get a cheap coilover kit like F&F or Tein. If you care about suspension dynamics and want to do things right, go with a custom (450+) spring rates setup with sleeves and a high end adjustable damper. There are hundreds of people on this forum that swear by Koni/GC, me being one of them, and you can get a complete kit for around $900 when reusing your OEM tophats. Best bang for the buck and performance hands down.

GC sells sleeves with Eibach coil springs. Stating "dampers that the GC coils sit on" is a bit misleading, as the coil sits on the GC sleeve, and the GC sleeve sits on the damper.

They aren't that inexpensive for 7th gens, see above.
I've been considering Progress Spring which gives 2" drop on the back and 1.8".
I guess to define my aggressive stance, it would be just to get ride of the gap between the tire and the fender. That would be it. I put in consideration that I'll be driving daily so I'mm leaning towards springs but would the drop of progress springs be enough for the stance I want? To get rid of that gap?

If you use springs, you'll still need to upgrade the struts to tokico blues at the minimum, but d-specs would be more appropriate.
Lowering springs will completely blow your struts out within a few months and you'll need to replace them and get an alignment. If your looking for a less expensive lowering option get tokico blues and a 1-1.5 inch lowering spring.
If you're getting a mild drop you should get Koni Srt.
Tokico blues are a different story, tons of people with 7th gens have been using them for years and continue to rave about them. Since they're proven to be a good, reliable damper on daily driven 7th gens they're what I recommend.
