I want my 96 integra ls to turn better and have a smoother ride. However, i don't know a damn thing about suspension. I would like to know what i need and what else is needed to put these parts on my car. I don't want to take it to the shop to get them installed and not have all the proper parts. I also do not know what engine upgrade i should get next because i have made all the upgrades i know of.

cold air intake
exhaust
headers
short shifter

yes i know its pathetic. Any help would be greatly appreciated.
