consolidated

I've adjusted the wing/trunk cover twice to no effect. I raised both sides to where the hood was tough to shut.

Any thoughts appreciated, hoping for an easy solution before taking it in. The knock is over bumps, I've checked for loose heat shields, exhaust, drop link/sway bar, brake ducts, harness bar...most of the accessible parts.

Sounds like loose sway bar end link.

My first thought as well, I'm going to recheck those.

Was this ever diagnosed?

I had those halo pipe sound everything I hit bumps, it sounds exactly like I hit my roll cage with a pen. I take the car in, end up it's a sway bar link was lose.

I recently had a knocking noise coming from the front end that I was sure was a loose sway bar link and sounded similar to, though not quite as loud as, the noise consolidated is getting. Turned out there is a brace on the front firewall which secures an air inlet for the climate control system and the bolts were loose. These kind of noises are maddening to me and often hard to locate so I was happy they found this one.

Hi! Did you diagnose the knocking sound? I have similar issue on gt2rs. Thanks!

Maybe Rear springs or loose endlinks... There is a technical bulletin from Porsche
About the spring issue

That does not sound good.

I have the Spring issue and my Dealer has ordered the parts and that is not what mine sounds like

Porsche checked everything and could’t locate where sound is coming from. Here’s the video attached. Terrible metal sound. Also checked the roll cage bolts and all is super tight.

The only thing i can think is the spring issue.... If you hear a metallic sound over bumps or when the spring is fastly compressed it s that problem caused by the absence of a rubber cover over the upper spirals of the springs... Porsche does the work under warranty installing new springs with the correct design

It has those covers, not a spring. Sound is driving me nuts. Actually when cold it does not have that sound. After a 20 minutes drive when car gets hot, than sounds is coming.

The spring issue was the main issue and had a recall and I suspect that must be it.
