Convertable Top hinge marks-Need feedback
You guys with Cabs...
My top is new Porsche, I've had it for just over a year. I always get deep hinge impressions, 2 on each side on the edge about to the rear of the door glass.
Yesterday I just noticed a small tear starting.
Does your tops also do this? Not the tear but deep hinge marks.
I'm thinking the top was not installed right or the hinges were bent.

Not sure what is going on there, Rockit. Here are a couple of shots of my now 19 1/2 year old top.
You can see the an impression on the passenger's side because I've been driving around top down this weekend but if I leave it up for a day or two and use some cab conditioner on it it goes away.

Those marks look like indentations caused by the pins (left/right) when the canvas does not fold correctly and get's pinched. Happened to me once and I always stop the top 3/4 down to ensure the top is folded correctly. Most likely that's what happened and not hinge marks. See a similar mark on the pictures provided with the previous post, especially on the passenger side.

The pins are nasty big spikes sticking up just waiting for your roof so that they can puncture it, argh!
There is a bar that is pulled back by elastic straps that in turn pulls the canvas back out of the way of the pins. However it doesn't always happen that way due to the loss of elasticity in those straps with time.
It is the bar that Holytin is saying to watch and make sure it's doing its job properly.
I know because I have matching holes through the canvas on both sides of my roof!

If these are from the pins as Holytin is suggesting it has nothing to do with hinges.

Root cause are the elastic straps that are broken or do not provide the correct tension to pull the canvas away from the poles while the top closes. I would expect that a professional installer gets this right and than it lasts for more than just 1 year.
Would be interested to see more pics of the strap in several positions of roof opening.

Another reason why manual operation is my preferred option. If you have to be out of the car to make sure it folds correctly, no reason to use a switch. You can't reach the switch and fold the top properly at the same time.

However, best thing to do is to pay attention to detail regardless. Happy hump-day!

You can see the bracket for the bar (piece with long part number on it) and it's in the correct position. You can see the large pin to the right that will puncture your roof if the bar isn't pushing the roof back. The wavy elastic under the part number on the bracket is the elastic on the passenger side and you have the same on the drivers side. Mine doesn't seem to have much tension to it anymore but lately my roof has been behaving and the bar has been pushing the canvas back.
You can also see a patch that was glued on from the inside by an upolstery shop to strengthen the roof on both sides where it's been punctured.
Hope this helps.
