The Konis alone will give you a big improvement in handling and overall control, with no drop whatsoever. Most people wnjoy the look and feel of a slightly stiffer and shorter spring though, I think you should throw on some Eibachs or H&R's while you're at it with the whole suspension apart!
Don't worry about the scraping... Some of us run way lower than the H&R's and still don't scrape. You need to be careful though, don't drive it like it's a rental Buick, over curbs, jumping speed bumps and hitting potholes on purpose!
