To get the same level of noise reduction, I am now up to 3 nickels. So the more pressure you put on the tab the more it bends and pretty quickly.

Hey Pete
I would bet the metal is not only different, but are both shaped differently and made of different metal The finish on the side looks totally different ( your old one is smooth and higher quality as opposed to the picture I shot That side of the metal looks unfinished and rolled ... ??
See a A -B comparison

Remove a tab from both the old and new roof. Take them each to the nearest university's engineering school. They should have a Rockwell Hardness tester. It will make a pin sized indent in the metal, not much larger than a few grains of sand.

This will tell you which metal is harder, and therefore stronger.

Made a startling discovery today when I removed the nickels. The tabs are fatigued so bad now in the closed position there is a 3/16 to 1/4" air gap making zero contact! I am going to post some pictures hopefully you can make out what I am showing. I wish I could post a video. No wonder I have so much wind noise at 70 and up! I did try an experiment. With the cruise set at 75 I can make the noise go away by simply pulling down on the forward part of the tab with two fingers. Very little force is required to make the wind noise disappear so if the tabs were not flexing there should be no issue.

The current metal tabs are just to malleable ... PERIOD
I could see that from the beginning !!
When I first put the roof in, those tabs were very snug ...
Within a few weeks the tension had completely disappeared ....
I really hope someone from Pilk is reading these threads ??
I think this could be an easy fix ? ...and I would be willing to pay a little to get a fix and help them out ...

Eddie: Can you make out from the pics I posted just how much of an air gap I now have in the "locked" position? I need a kid to help me post a video. The damn thing is literally flopping in the wind like a tarp now. I will go to HD and get some stick on rubber feet tonight for another temporary fix.

Crazy Eddie

Yes I can because I know how this metal bends so easily
If you put rubber in there its only going to bend even more
You will solve it for a few days or week but its going to bend even more

Crazy Eddie

I just spoke to Pilk and they are truly working on this ....
They realize there is an issue and and working on a fix....
That to me is great news ....
It seems it is what we suspected ... there is an issue with the malleability of the metal ? But they are still doing testing
So we need to sit tight and wait for them to come up with a solution.
The person I spoke to today said he was sorry for not getting back to me when I called earlier, after he came back from vacation...
So, I think we are on the right track now
Best regards
Ed

You rock.

What is a vacation, and how come the person you need is always on one? :-)

Crazy Eddie

LOL
I assume it was a vacation
I should have followed up when they didn't call back originally, but got a little pissed and lazy...
I have not used spaces to make it tighter, just because I figured it would only bend it more ....
Just looking at the picture of your old sun roof latches makes me think the metal is totally different .... and its shaped differently ...

Hi all, I am having similar problems with my new top, when I first fitted it the drivers side catch (rhs i'm in blighty!) was so tight that the plastic catch distorted while i was trying to close it. After it had been on for a week or so while driving I couldn't understand where all the noise was coming from, suddenly realised that both catches had fallen open. When I went to close them they were so loose that I had to get my daughter to fold up some paper and stuff it under the metal tabs. This paper is still there. I still get a lot of noise over 100 at the moment but at 80-90 it's pretty quiet. I have just purchased some M6 brass threaded black bakelite wing nuts from ebay and was going to remove the original fixings and replace them with s/steel coachbolts so I have a tightenable set-up. I just thought I'd check on here and surprise you are all having similar problems. Keep me posted with Pilk if you can, I just left a message from here but I doubt if they will call the UK back!

I think it's a great product just needs a bit of tweaking which they really should have done, my 951 has a very dark Marineblau interior so it's a great improvement! Much better than the solid roof. I'll take some pics at the w/e regards Jon

After reading these updates, I looked at mine again....and drove it at 70 MPH. I still do not have the reported issues. I purchased mine right around December 1, 2013. Wonder if the issues will manifest or if there was any revision to the design. Will report back with future developments.

I see that your are from Chicago, IL, so not a year-round car and definitely not exposed to sun year-round.



I'm still suspicious that the cars in warmer climates are more prone to failure.


The rubber grommets that hold the latches to the glass itself may be failing due to heat.

Guys we live in Northern CA.... (Eric, Pete and I )
The ave temp is around 74 degrees here
Day time 70-80
Nightime 48-55
This aint TX
My car is in the garage 23 out of 24 hrs a day
This has nothing to do with the temps, trust me
Regards

No noise on my roof, and my car has spent a considerable amount of time outside since I installed it.
