There's **** tons of torque in those things to pop up a heavy metal deck lid. They're under a ton of strain when closed so yes, that could easily distort your deck lid. You maybe have to consider taking the torsion bars out and use a prop rod when you need to keep the trunk open.I mean the trunk has like a general curve. I've heard that it has to do with the tension rods/springs that are in the trunk, that they're somehow too heavy duty for the fiberglass since they were intended for metal or something, and that may cause the trunk lid to curve a little. Any word on this?
