It all depends what you are using it for and how much dough you want to fork out. Drop spindles are probably the cheapest way to go but there other options. I also want to do this but I want an adjustable drop and tight suspension. You could get Firestone air bags and a pump tank etc. but I think its not worth it for the price and the of space it takes up. A site scandc.com has an option I want to take eventually. They make tubular upper and lower a arms that come with tall ball joints and it lowers you about .75" Not enough but they also sell coil over kits that can adjust hight with a wrench and stiffness with a knob. All together with the stage two kit and all that stuff it's about $1200.00. Professional stuff but it will cost you. It all depends again on what you are using it for (car shows, daily driving, drag racing, circle track, etc) and how big your pocket book is. most average drivers just get drop spindles. Be careful if you chose springs too. They can throw off your geometry and make it handle erratically. that's my two cents.
