I knew all of this stuff about cheap coil overs but I took the chance for the money. I had my buddy install them for me. Yes you do have to cut make some changes to get them to fit. However, my buddy said it wasn't a problem at all and I've had them on for over a year. No problems at all. Adjusts very easily and gives my car much better look. For handling though I also had him install KYB GR-2 shocks and struts. I found a good deal on ebay for them for about 120. If you're looking for big performance don't buy anything cheap. However for me, right now I'm not looking to even start messing with turbos for another year because I'm a student and I need a reliable car. Plus I don't know enough yet. However those cheap coil overs worked great for me for looks, and for the handling I got some decent shocks and struts. Whatever works best for you.
