an easy way to adjust would be to raise top enough so you can access the cable motor in the middle of clam shell near trunk lid (see photo).

whichever side is higher disconnect the opposite cable, then from inside the car using the top switch tap it a couple of times close then reconnect the cable and close all the way.

Suggestion
When replacing my transmission and cables for the top I did not have one side correctly attached and it did bind a bit preventing top complete closure of the clam shell.

Coverage and how to read this overview
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.

One side of my clamshell is a little bit loose and does not lock completely on closed state (comparing to another side). I checked V lever and it’s identical both sides. “bad” side edge sits a little bit higher than good one. I think as “closed” lid position corresponds to two different V lever rotations it has to be either V lever transmission axis offset or some bad (weak spring?) rod. Eccentric bolt has almost zero effect on the situations. It fills like in both roof up and roof down scenarios there is not enough tension on “bad” side to hold lid down.
You can adjust the position of the lid by using a drill directly connected to the transmission cable.
You will have to do that with the lid open though.
Wait I know this one! It just happened to me... Double check your cables from the top. One side of mine had popped off and that made the clamshell stick up a little when closing the top.
You had mentioned in an earlier post about the noise behind drivers shoulder, I am assuming the "bad" side is the drivers side.
Look at part labeled 21 in diagram, it is a plastic cover attaching to the glide rail.
It connects via two tabs that slide over the glide rail, you can either just slide off to remove and see if that may be the issue of them binding on the glide rail when closing.
When replacing my transmission and cables for the top I did not have one side correctly attached and it did bind a bit preventing top complete closure of the clam shell.
Takes quite a bit of force to bend the clam shell permanently as they are made to be flexible.
Good luck
I suspect "noise" is quite natural in my case as "bad" side is not completely flat/tight. So it moves a little under load. I have no idea what clamshell is bent. As many boxster owners I'm poor guy who bought it after many owners. I only removed cover to verify that transmission is original and bolted in factory and I did not find any trace on the body of some collision repair. But shell really looks skewed. There is visible gap difference between "good" and "bad" side.
I have very close to what in

whichever side is higher disconnect the opposite cable, then from inside the car using the top switch tap it a couple of times close then reconnect the cable and close all the way. Might have to do this a couple of times to adjust.
I know this thread is a few years old and I am new to the forum. I was hoping someone out there could still comment on this.
I have a similar problem. On mine, the passenger side of the clam shell doesn’t close all the way when the top is fully down. The clam shell closes fine when the top is up. I’m curious if removing the opposite side cable will work for the fully down application as well. Thanks!
Have you tried making sure the top is not bunching up or causing the issue.
When I lower mine I lower it part way then make sure the plastic window is laying in with no creases or folds.then lower it more check again rinse repeat.
