car specs
1998 accord coupe v6 ex
215/45/17
generic coilover
stock shocks


this past weekend, i found that my tires were completely stripped on the inner edge of tire. it was because my tires were rubbing up against the edge of the shock ring (the circle thing that holds the spring up). my ride was quite low. so after i replaced the tires, i adjusted the coilovers a lot higher. now every little bump i hit on the road, i hear this REALLY LOUD CLUNK noise coming from all 4 suspension(especially the front). however, when my car was adjusted lower, i didn't have this big of a problem.

first question: how the hell do i fix this noise problem? is it hitting against something, and is it damaging my suspension?
second question: how do i make my tires parallel to the road (what is a lower/upper tie bar or camber kit thing?)
third question: if i get a tie bar or camber kit thing, will my tires still hit against anything if i were to lower my car?
fourth question: will i need an alignment after installing a camber kit or lower/upper tie bar?

any help would be appreciated. thanks!
