Has anyone who installed the G4 OEM rear spoiler swapped out the trunk lid torsion bars? I installed the rear spoiler but didn't swap out the torsion bars and the trunk lid stays up as normal with the new spoiler attached. I would imagine these new torsion bars are stronger for holding up the trunk lid with the new spoiler. I'm going to see how it does but if it doesn't hold very well i will swap them out. Heck i might even do it the next couple of weeks for the hell of it.
