I would like to install a turbo decklid on my 996-2 C4S and see that I need to exchange the filler piece between the rear window and the decklid with the turbo body fill piece.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I would like to install a turbo decklid on my 996-2 C4S and see that I need to exchange the filler piece between the rear window and the decklid with the turbo body fill piece. The filler piece that needs to be exchanged is where the third brake light is currently mounted, the new thinner (by a inch or so) piece will not have a third light mount as the third light will relocate to the decklid wing area. So my question is how to remove the filler piece!? Different blogs advise to either remove the mounting torx screws (three under the back edge accessible under the decklid and a couple from the interior under the firewall cover and insulation); snap it out - it will suddenly break away with a click or snap; or it is welded in and will require body work by a shop to remove. My vehicle does not have the rear window wiper, so the only penetration in the filler piece is for the third brake light.
Question - has anyone done this before on a 2003 C4S Coupe (i.e., not Convertible) that can clarify what action I need to take to remove and install the Turbo filler piece? A web link to a technical solution also would help!
Why? the turbo wings leak fluid and break all the time. Dealer wants up to $3k to fix it and the two aftermarket solutions I know of are b/t 1.2 and 2.7k. The c4s looks better w/o a wing, its smooth and the red strip is cool.
I�m sure most will simply comment that such is blasphemy, but it�s your car: follow your dreams. Can�t wait to see how it turns out!
And please do keep us posted. I keep thinking I�d like to do the same but wanna wait until I get some other styling bits squared before I make the leap.
Loren on Renntech is a guru. I'd follow the instructions at the link above.
Oh, and let me know if you need a turbo decklid. I have a turbo decklid in terrific condition, with the wing, and some low fixed mounts. I bought it from a rennlister (I was going to modify it to fit my C2) but decided to go in a different direction.
Thank you for the responses - however the link (
https://www.renntech.org/forums/topi...on-my-c4s-cab/
) is for a Cab, not Coupe. The Turbo decklid fits the C4S Cab, but not the C4S Coupe - the filler piece between the rear window and the decklid (it houses the third brake light on the C4S) needs to be exchanged with a filler piece from the Turbo and in doing so the third light is operational in the wing are of the decklid. So, I am still on the hunt for information on how to remove this piece would be most appreciated. Again, the vehicle is a 2003 996-2 C4S. Thank you again!!!
Make sure you unplug wiring harness & sensor first. I�ve gone back & forth between my OEM rear deck lid and my TechArt - all I had to do were to remove 4 bolts (2 on each side - see pics) and then transfer several pieces over.
Thank you for the feed back! Unfortunately what I have is a true Turbo decklid and it won't swap across without changing out the third light filler piece with a Turbo (non third light) filler piece! I wish my solution was a simple and straight forward as yours. Thank you again for sharing - you have a beautiful car!
