i'm planning on replacing the shocks (stock) on my 92sentra. i want a decent brand since i'll be lowering and replacing the springs as well with a h&r set that i bought from 'Subie 2.5 sti' (thanks again Subie!). He mentioned tokico is a good brand. but i would like to know, what exactly am i looking for when buying a good set? please advise. thank you in advance.
