A couple questions:

1)does anyone have a handle on how much the performance springs/bilstein
sportshock combo will lower an xi?

2) if one were going to change out dampers and springs, what other specific componants, bushings, etc, should be changed out at the same time to save labor costs? And are there specific mfg recomendations?

3) is it critical to change rear sway bar as well, or would most street driven vehicles be fine stopping at dampers and springs?
1) I believe the rear drop would be the same as the RWD and the front will a little higher. While not visually ideal, from a reliability and performance standpoint this is fine.

2) It depends on the age and mileage of your car. At somepoint the bushings will have to be replaced. But if you aren't tracking it and you're under 60-80k miles, you should be fine. There is no hurry, just replace them when the old ones are worn.

3) Totally up to you. As CobraMarty showed, it is an expensive proposition to replace the rear bar. I'd do springs/shocks first, and if you want a little "sportier" ride, then you can look at replacing the rear bar. But, while you're under there replace the rear subframe bushings to save on labor costs.
