Hi Guys - The targa part of my roof has blown off - do not drive the car much with the roof on, only when wet so does not get used much.

However my daily driver broke down so used the Chimaera. Nice blat up the motorway pressing on with roof, as I,m wearing a suit and pop - the roofs gone. Lucky it did not hit anyone and found it in the verge a bit sad looking but o/k

Had a look at the fitting - removed the rubber from around the windscreen and it would appear that the roof lip does not go far enough under the metal ridge of the widscreen support because when fitted and pressure from underneath applied, the roof lip comes out from behind the metal ridge so that the rubber gasket which is glued on is all that is holding down the targa section.

The back section is fine and works perfect, and cannot see how the targa part could be made to move further under the metal ridge.

Looking for a solution am thinking of adding some ali flat onto the roof lip to get a more positive location under the metal ridge of the windscreen hoop.

Would welcome any advise, experience please

Andy

god that must have made you kack it a bit! good job nobody was behind!!

can you re-align the roll-bar / roof hoop / whatever you want to call it so it pushes the panel harder into the windscreen recess?

Peter - it was very scary - the sudden pressure difference gave me quite a jolt, and when I realised what had happened my concern was for those behind - very lucky to get away with it.

The back section does not look adjustable, even if it could get more forward pressure I don,t think it would be enough to compress the gasket more to get more lip under the ridge.

Hi Andy,

I used to have slight roof problems on mine a bit - what was happening was that the captive nuts that hold the bolts that hold the hoop on had broken away from their mountings. The fibreglass had cracked under the tension over the years I guess. As such the bolt was at an odd angle. Roof still worked ok but didn't close properly.


Have you peeled back the carpet and made sure the bolts are tight and true?

Thanks guys - the rear section seems ok, but will check bolt location / condition tomorrow - thats a very nice offer, but my targa stucture seems to have survived, the covering is torn and stained after its high speed trip across tarmac and into the verge and am going to recover it when I have considered any modifications - Andy

Surface and Design split my Griffith roof in two, and one of the mods they carried out to the panels was to extend the front lips of the panels where they mate to the top of the windscreen. I think the reasoning was that the two individual halves didnt get as much support as the curved single section when it was just sat in the lip waiting for the rear section to be brought up and into place.

You could peel whats left of the fabric off and try to extend these. However you if using fibreglass to extend the panels, you will need to make sure that it becomes an integral part of the panel and not something that will stress fracture under the weight of the roof you put the roof panel back on.

Your plan to use an Aluminium extension piece might be the easiest way.

Alternatively, you could unbolt the foldable locking arms on the rear roof section at their lowest point and pack them off from the rear bulkhead. This should give you a bit more force to hold the front panel in.
