Had a similar noise/tapping feel from the front end of wife's BMW 530i and the dealer couldn't fix it. Several months later when it went in for a different issue and was told have bent wheels up front

They straightened the wheels and the noise is almost gone.

Yeah I know it shouldn't fix the problem but it really did and yours sounds exactly like hers

I recently had a “test drive” on a 991.2 GT3 that I’m interested to buy. I notice that on the rear right, when you bump hard, a metallic noise coming. Anyone had the chance to understand how to solve it? Is this something normal or we need to consider it as a car issue? This will help me on buying. Thanks for help.

Should be relatively quiet over bumps. Not luxury sedan levels of isolation, but nothing should sound broken.

This sort of a clunk can also indicate worn struts, basically the center polished shaft of the strut develops play inside the housing.

Is this something that it could be detected and easily fixed from Porsche center? Car is under warannty.

It was a guy that posted a video at the ring that had same noise.
Basically, When the car will meet at high speed a dip or bump and seems to go at full load, it make this noise.

Hard to do under load, but with the wheel off and suspension free hanging, if you grab the top and bottom side of the rotor and attemp to wiggle vertically (top hand push, bottom pull then swap direction rapidly).
