SVT springs will not lower your car one bit.
Struts at 60K miles are not worth the effort or money to put on your car.
This really doesn't sound like what you want at all.
I personally favor the BAT European Handling kit. It's $599 for new struts and springs and it lowers the car about an inch. You could go with Koni struts and H&R or Eibach springs, and those lower the car over an inch. This solution is expensive, however, since the Konis are around $150+ each.
