Losing my mind

Everytime I change strings on my Ibanez RG5120M the setup gets all messed up. The string action gets too hight, I have to tighten the springs and I hate it. I use 10-46 strings in E standard and the springs are tightened as FAR AS THEY WILL GO. And still the f**king trem needs to go down slightly. Also my string height at the 12th fret is 2mm and I like it at 1,5 mm. My ltd m-1000 has no problems what so ever. There’s room for tightening the strings and I can lower my bridge even more if I wanted. But my ibanez has the bridge as far down as it’ll go, and the springs as tight as they’ll be, I even angled them so they’d have even more tension, but still it’s not enough. Neck is straight so that’s not a problem
