Sorry to revive a kind of older thread, but while I was tidying up in my boot today, I thought I would see if I can make my boot pop up higher. Because I have a spoiler and a heavy number plate, my boot barely even pops up above the latch. I had a look to see if I could make any adjustments without buying anything extra, then I remembered that useless quote from njerald saying to adjust the torsion bars, but not stating how for everyone else.
So this is what I did, just in case anyone wanted to try this first.
Firstly unhook the torsion bars from the retainer in the centre of the boot area:
Then fold back or remove the carpeting from the side of the boot and look for the hole where the torsion bar slots into:
Then pull the torsion bar out and move it to a higher hole. Going higher increases the tension, going lower will reduce it:
Repeat this on the other side, then place the torsion bars back into their retainer like in step one, and you should now find your boot lifting up with a little more strength. Depending on your case, this may improve it enough so that you don't need to get that rubber strap.
I didn't want to go for the strap idea because of the way that it pulls on the linkages for the boot. Over time, I worry that it may affect the way the boot opens as the arms would get slightly bent under all the tension from the straps.
watch out adjusting tension, when you open the boot in windy conditions, the corners of the bootlid will come in contact with the rear window. mine has done this a couple of times and it worries me that it will break the glass ! <_<
