how low you plan on goin? i got h&r sport and i love em...its better then the skunk2 coilovers i had on b4...hurt my back..even with tokico shocks back was still bouncy...

and for tryin to do it urself i agree with what the person above me said "it just depends on you, and the tools available to you."

you can look on team-integra.net website they have instructions on how to do it

almost forgot to tell you it is recomended that you should get shocks along with the springs and installed it then..itll save you from a world of hurt
