If you're only changing springs, not struts or coilovers, you only need to unbolt the top nut, the brake line clip, and the swaybar nut. The springs are on so little static load that you can unbolt the nut and let the spring decompress as you raise the car. You just need to be careful fishing it out of the fender. The only special tools needed are a pass-through socket set and long allen wrenches.
