The Koni STR.Ts definitely wouldn't be a bad choice, depending on the specific springs. The issue with these Konis is that they are fairly stiff, and combining them with a fairly aggressive set of springs (like Steeda competitions) would probably hurt your ride quality for your daily drive. If you're using more mild springs (with 1.0" or so of lowering all they way around), you should be in okay shape. That being said, the Koni Sports are able to adjust softer than the STR.Ts, and make for a better street ride. Granted, they are MUCH more expensive, and aren't in everyone's budget. Still, the STR.Ts are a good choice, depending on the spring.
