Still a strange noise

I have a small clunking sound from my right rear suspension. It occurs when I go over bumps and the car is cold. I just took to shop to fix twice. 1st time they tightened and greeted sway bar bushings. 2nd time replaced bushings and sway bar links. What would warm up and then stop making a noise? The shop said everything looked good. They checked and retorqued the strut mounts. Could it be something as simple as the roof frame bouncing a bit. It occurs whether the roof is up or down. It drives fine and straight. I'm stumped. The shop is all ex porsche dealer guys so I'm assuming they know what they are doing. Suggestions?

I realized last night that the noise is still there when warm, just not as much.
It's a long shot but maybe the right side cable that holds the roof down needs to be adjusted. Maybe the frame is just bouncing a little bit.

Metoo.....
But only when warm and below 30 mph.
Got so used to it now after 5 years that I would probably miss the clonks if they disappeared!

Rear track arms will solve the problem. TRW has good ones. Good luck.

If it's that obvious, I'm surprised my mechanic didn't realize it. They replaced the rear drop links. How would they test?

The brake or acceleration test. If rattle goes away under acceleration or braking over a bump its the trailing arms.

When I bought my first Boxster two years ago the independent I bought it from swore that the rattle couldn't be from the trailing arms. I found a set of used Cayman trailing arms and replaced them myself. Rattle gone.
