regardless of what others may say, First of all- it is your car to do w/ what you want. Second - you are starting right by doing research. knowledge is power. springs are an economical way to lower a vehicle but w/ a price (unless you also change out shocks & struts to accommodate the change), coilovers are a good option but there are cheap options as well as high end quality ones, and then there is the baggit option-can fall into same categories as the coilovers from cheap to extravagant. you have to figure out the type of driving you do, the budget you have, pros & cons of each system. there is a saying that "custom don't come in a box" so if there is something specific you want to accomplish and there isnt an off the shelf version, doesn't mean it can't be accomplished.
