Not sure what other mounts and bushings you are referring to, but springs are a strait swap. Others will do other bushings and what not as an upgrade at the same time, but nothing else is required to do springs.
I would suggest the Hotchkis springs. They will feel very similar to stock as they offer a progressive spring rate. Feel free to call, PM or email me anytime with questions.
