O bad memories, somebody once posted a tool that helps you move the bars without killing yourself it was a bar with 2 holes in it. I was never able to find it online.
I ended up using a locking plier and brute force, it slipped once and nearly blinded me.
Thankfully I was wearing goggles.
Those springs are not fun to deal with at all. I found even fully torsioned in the highest spot it would just hold the trunk open with a spoiler.
The story I've heard is, if the car came with a spoiler from the factory you got a heavier torsion rod. Everyone else got the standard 2 rods.
To correctly setup the rods they should be torsioned so when you pop the key, the lid should rise up about 6 inches by itself.
There should also be an anti rattle clip that holds both rods together in the center, I just keeps the rods from making noise where they touch in the cross over.
Be really careful when installing them wear a thick long sleeve shirt and goggles. When the springs slip back off and just let it pop and then try again. Use a piece of wood to prop up the trunk lid also. Keep it open fully.
What makes the springs dangerous is you have to twist them 180 degrees from one end to the other to fit them into the mounts that twist is what gives the power to open the trunk lid. Once you start to torsion the spring it holds a lot of force and at that point it can slip out of your hand or out of the mount holding the end, once it starts to slip in a nano second it will pop and release all its energy, don't be there when that happens.
