so why does it unscew why are their lines on the roof like a targa

thanks

it is not a targa....the roof is carbon fiber so it looks similar to the transparent C6 targa top....

I completely agree to the title of this thread sorry, but it was kinda funny.

The roof panel is a separate piece that is added at vehicle assembly. On the Z06 and ZR1, the panel is made to bolt in place. Those bolts are hidden above the headliner. It was not made to be taken off by the owner but can be removed for repair and replacement by a mechanic. So yes it looks like a targa coupe but the roof doesn't latch in place like a targa coupe.

I didn't know this either. I guess there really are no stupid questions. :o

Unlike the 01 thru 04 model Z06 roofs which didn't even remotely look like the targa roof coupes, all of the C6 generation coupes and Z06s have separate roof skins that are installed with adhesive to a separate roof frame. For the Z06s, the metal frame is a magnesium alloy. As a matter of fact assuming no changes over the past two years, all roof panels are finish painted outside of the Bowling Green assembly plant by the supplier that makes the roof panels. Sometimes GM has color match issues as a result like when they had DSOM. The match between the roofs and the rest of the body panels wasn't up to quality standards. It was a tough color to match including the outside mirrors which are once again finish painted by the outside supplier. So to conclude, the targa roofs are made to latch in place for owner removal and the Z06 roofs simply bolt-in and covered by the headliner because it was not intended for owner removal. Hope this was helpful to those that didn't know.

yes it was thank you very much

so does this mean that with the right tools and hardware, you could essentially unbolt your ZR1 or Z06 roof, swap hardware/add parts, and pop in a targa roof. I know its a long shot but figured I'd ask

GOLD72

Frankly I don't know the answer to that. The roof bows and windshield frames may be different to accomodate the latches on the coupes and bolting on the Z06s/ZR1s. If it was simply changing bracket attachments, then it might be possible. I will see if I can find my old photos of the Z06 publicity birdcage frame photos from 3 years ago to see if I can see the attachment details.

With the right tools and hardware, the simple answer is "yes, however". the halo frame is not the same as in the coupe. In addition, there is a flex concern within the car's aluminum frame. There are several threads that address this issue in the Z06 section. Either way, it's not a Do-It-Yourself project

Exactly

Exactly what I was thinking! I still remember my '93 40th anniversary Vette with a Targa top. The top adds a lot of stability. The difference driving the same car with the top on and off, was night and day. With the top off it felt like the front drivers side front was bouncing around when you got on it, I could really feel it in the steering. Top on it felt just fine. With the aluminum frame, I think this effect would be worse, let alone 638HP!

Actually the C4 Targa was a structural part of the car. Handling with the Targa on or off was like two different cars. It's one of the reasons the C4 Targa was attached with screws that had to be removed instead of just latches.

C5's and C6's on the otherhand were designed in such a way, think hydroformed frame rails, that the handling is basically identical with the Targa on or off. Even the Convertible models have very little difference in handling compared to the Coupe.

The Z06 and ZR1 with their aluminum frames do have more body flex and is the main reason for their fixed roofs. A conversion could be done but at the expense of handling which may or may not concern the person wanting the conversion.

The roof does not come off, like the ZO6.

From what I can see in photos, someone will have to be good at metal working and welding aluminum to be able to do a targa roof conversion of a Z06 or ZR1 with its aluminum birdcage.
