			In general, springs control the height of the car.   Theoretically, you can keep your suspension in place and just replace the springs (although I never researched that).
 Better suspension systems are out there though.  Search for "coilovers".  A coilover has a strut + spring together.  In many cases they are adjustable dampening (more/less firm).  They are also typically threaded to allow you to set the height of the car precisely.
 
 Search for KW Variant 3, or Bilstein PSS10.   These systems are big bucks.
 
 There are lots of other possibilities that other folks will tell you about too.
 
 Good luck with it.

			This will be argued but there are 3 ways.  1. you buy HR or some similar set of lowering coil springs. You remove your struts install the new coils and put your original struts and new coils on.  This gives you about an 1" to 2" of lowering. You loose that amount of travel in your suspension. You could get some bottoming of the strut and harsh ride. The height you buy is what you have
 2. Buy a ROW setup or Bilstine strut set not adjustable. They are made to ride lower as a set. Better ride than just the spring because you still have all the travel and the pistons are designed for the ride level you end up with. The ride will be stiffer. you should not experience any bottoming. Again you get about 1" lowering.
 3. You buy an adjustable strut set. There is a wide range of these. The spring perch is adjustable. The strut is designed with more valves and better baffle so it controls the oil flow in multiple levels and both directions. Some manufactures sell different springs to adapt to the ride or performance you want. You can change the height of the ride based on driving or ride preference. Most have 20 to 36 hydraulic settings to soften the rate. They can be as smooth as your original strut or race ready and very stiff.

The best way to control your ride height and maintain quality suspension tuning is with coilovers.

			Where are you folks getting your coilovers and what brands are you running?
 I know there's Bilstein PSS9/10, KW, H&R, JIC...all $2000+
 
 There are some on ebay (D2, etc.) that are at a more reasonable range of $1xxx...anyone running those?

			PSS9s on my car.  Some say that they are not fully up to the task but I have no complaints.  I've never been one to go with the lowest bidder on a critical part like struts.  I prefer well tested over lowest price.  YMMV

I am also looking for this option (D2). If you find a place that ship to France please let me know. No pss9 or H&R for me. I don't want to spend too much because of the age of my car. Just need it lowered.
