spring is not adjustible. It will drop you a certain hieght and thats it. If you get coilovers you will be able to change the hieght, so if you want to be able change the ride hieght go with the coilovers. About the coilovers messing up the suspension fast, i think that is only because that is with stock shocks, if you get springs that drop enough, they will mess up stock shocks as well. Hope this helped
