Im not looking to make a huge change, just a very minor one!! Is that how i would do it though, just by adjusting the springs a tiny bit?
If it's just the bar/arm that is too tight or loose, you can just buy a replacement bar+arm socket. Pull off the spring cavity and you should see a hex screw on the underside of the floyd bridge. Loosen it and remove the socket and tighten on the new one. I've done this twice my friend and it'll take 2 minutes. The springs are the tension forces acting on the entire bridge. I'm not sure you can adjust them other than adding or removing them.
