I have heard mixed reviews on Tein S techs. Their really good quality for name brand springs, but some ride horrible. I get instant response, but then again, I am using Moog, KYB, and Prothane pieces. I know the AC Delco strut mount bushing is horribly designed, thats why I went with Moog.
Far as clearance goes, mine is a bit over 2 fingers gap, perfect IMO for clean DD'ing. Some people prefer tire tuck method, but thats up to the owner for when it comes to cornering. I have also heard Eibach sway bars are horrible, but I have owned a set for my Suuby, ran beautifully. Its all based to the owners opinion. If you expect a whole lot from just a few bolt on pieces, you need to upgrade even more. I have owned as well GT Spec H brace for my MSP with a whole suspension overhaul and sway bars. That brace made the biggest improvement, but required every bit of suspension upgrade to make the difference.
