Mod: Simple 'No-roof-wear-from-trunk-liner' fix
« on: May 07, 2010, 09:42:36 AM »
I first saw this problem at MD mod meet 6 where DBG pointed out at least one owner's roof worn through contact with the trunk liner.  The problem occurs at the rear fold where the sides of the roof crease out and the points of the creases rub against the side walls of the trunk liner.  If you raise and lower your roof enough times this wear issue will happen to you!

Going to MMM7 last week reminded me that I was going to do something about it, hence this mod.  Basically all it is is the addition of a drilled hole and a push pin on each side to cinch the carpet liner back tight against the trunk wall, away from the roof crease point.  Takes maybe 10mins a side if you do it slow.

Even if you don't believe you will get this wear problem, I found that the mod (surprisingly) allows the roof to close down far more easily now, requiring little or no pushing down before closing the trunk.

OK, so this photo shows the wear point (passenger side) that I'm talking about...

[ Guests cannot view attachments ]


First put a strip of masking tape where the roof crease is, marking the point where it touches the liner.  Then press against the liner with your finger and find a place about an inch back from the crease point where the carpet liner is most easily pushed back to the inner wall.  Mark with an "X"  (Note: I found this was not at exactly the same point on each side of the trunk due to differences in the liner shape.)

Now, using an awl or other sharp pointed instrument, make a hole in the carpet at the X and while pushing the carpet back against the wall, scribe a mark in the inner plastic with the point, where you'll need to drill.

Pull the liner out and away and carefully drill a hole in the trunk wall.  DO NOT go too far or you might hit something behind. :)  You'll also need to enlarge the hole in the carpet....  I did mine by melting a larger hole with a propane-torch-heated philips screwdriver.

Now put the liner back in place, push against the wall, lining up the inner and outer holes, and insert your clip.  You could use a regular "christmas-tree" panel pin, but I preferred the expanding type with the screw-in center post.  It's a firmer lock, and yet is easily removable if you need to get back in there or ever get the liner out.

Here's the pin in place, carpet cinched back:

Rinse, repeat, for the other side...

... and the end result, showing the clearance...

EDIT:  For people asking about clips/pins, this is what I used.  Got mine from  Pep Boys ($2), but seen them (or similar) at Advanced Auto and similar stores.  These ones take a 1/4" drill bit for the holes...

Good luck!!

Took a look at lunch time, my top doesn't touch the sides, close on one side but a good 1/2" or better on the other.  Great idea though

I have been thinking about adding a little dent where the top meets the wheel well, that's what binds the top and keeps it from just dropping into place and I think with a little dent there it would be perfect

1st I like to say Hi from SKYROADSTER>COM to all.
This is my 2nd posting. And will start reading asap.
I will check my 08 R/L PW for this and repair same if needed.
What a great mod. I know if it were not for these two sites. My SKY would be damage by now.
Thank you,

Great mod, TS!  I just did it and it took all of 5 minutes to prevent unnecessary wear on the top.  One has to wonder why they didn't come this way from the factory!

The most weird thing, to me, about this mod is that I can't come up with a reason or a way to make it more complicated  :huh:

Well done!

I need to see if mine touches there. I bet it is as its hard to push down enough to close the trunk.

Mine barely touched at the creases but still needed a solid push on the hoops to go all the way down. 

After doing the mod, the roof just drops into place.  I think the reason for this easier closing is that with the liner pulled back against the walls, it is removing resistance to the roof in places lower down, closer to the floor, that you can't normally see with the roof down.

Thus, this is a good mod to do, even if you believe yours is not subject to the wear issue.
