I wanna get lowering springs. Hotchkis or h.techs; but I wanna know how long, under fairly decent driving conditions, until I will need new shocks...

 

Well... I have Hotchkis and I've probably put well over 10k on since I got them (no new shocks). There are a lot of people probably over 20k at least even. But that doesn't mean that yours will or won't hold out just as long. They seem to be holding up well though, so I don't think you'd have to plan on them anytime soon. I would guess within a couple years.
