yeah i would definately watch out for bad coilovers i know all about that. but like i said the only problem to watch with springs is their spring rate because they may sit as well as compress a lot lower than they should. but most of the bargain springs are sold by lowrider shops for people (like me) who want the lowest ride possible, so if your looking for a pro-kit type drop less than 2 inches, stay away from the cheepies
