Default trunk lid opening??

My best freind just got a 05 C-Class yesterday, when he pops the trunk the lid opens up all the way. there is a spring in there that allows it to do this. I know that Cadillacs and some Buicks do that also. I went investigating into my own trunk and found that the trunk lid is used with a torsion bar of sorts, there are different slots to adjust the bars. anyone with a FSM know how to adjust the bars to make the lid pop all the way up?

cranking town a torsion setup to give it enough spring to pop right open ... MIGHT put too much stress on the mounting points and start to kink/bend the trunk when it'* closed

if anything I'd just suggest a pair of cheap small hatchback struts... same idea at the hood struts.. (if your car has those... mine does and sometimes I forget I've got a delta not a bonne )

your trunk will pop up all the way if you want to be a bubble butt. I found this out on both my 1994 and 1999. That spoiler IS heavy -to a point.

The spoiler isn't heavy on a 93ish model year at all! The trick is that the trunk is near perfect balance, just a lil more spring to pop it up.

With my trunk lid carpet, my trunk goes about 1-2" up when i pop it, I like this, because even in not so fun wind, the trunk doesn't fly open and stress anything.

If you move the torsion bar to the slot nearest the rear of the car, that'* the most lift you're going to get. It'* *supposed* to be adjusted to make the trunk lid seem weightless.

my bars are on the first noch towards the front of the car on the left side and second noch to the front of the car on the second side

The 2000+ models do this incaseyou didn't know. I can see good and bad in this. The good being that if your hands are full you can put stuff right in, the bad, if you accidently pop your trunk without knowing it, it'* goign to pop wide open and people are going to notice it'* opened a whole lot easier than if it'* only popped 1 or 2 inches.

mine doesn't pop up at all. you hit the button and go pick it up. maybe my springs are weak? it has no spoiler too.
