coilover springs???

I'm looking for adjustable springs for my mazda 3? Tein is nice....but is there anywhere to get just the springs without the shocks? do they make those? Please help.

Most likely Eibach springs will have a size that works (they have many different sizes.)  You need to know what spring rate you would want.

You do realize that the adjustability is in the shock not the spring, right? (threaded collar on shock can be moved up/down the body of the shock to either increase or decrease the preload being applied to the spring at ride height.)
