Took delivery of my manual 1.2 GT3 - doing break in miles presently, just about 500 on the clock so far

Noticed when at freeway (or higher) speeds, if the car hits an expansion joint or a rough bump/transition (e.g. highway 'bridge') that makes the car jump or jolt up and unload suddenly, there is always a loud, single metallic clank/clunk at the peak of unloading that comes out of the rear end... if I were to guess it seems to be coming from the top mount area (and not from low on the car, e.g. wheels or brakes area)... doesn't do this on the front end... just the rear

Anyone else notice this in their cars? Neither of my 1.1 GT3's do this.

I know they put in stiffer springs all around in this new version... it almost sounds like a mono ball clank or when an aftermarket suspension lacks enough travel

My dealer had one of their very experienced techs do the PDI... can't imagine they messed that up...

Interesting observation...because I noticed that same sound in my GT3.2 PDK, and while I wasn't 100% sure, I put it down to some movement roll cage which itself does occasionally rattle (but that is a different sound). Then I got my Touring, and sure enough, I get the same sound on an infrequent basis coming from the rear. So it can't be the roll cage!

I have been told its normal but not what actually makes the sound. My Touring goes in for a Post Track inspection next week and I am going to ask them to take a look and at least explain to me what cause the sound.

Noticed the same noise on mine as well. Chalked it up to another "GT3" sound from the stiff springs on any bump the car goes over at speed? Keep us posted OP/Chris if you learn differently

Same here....happened multiple times on my '15.....a very unsettling noise but learned it was normal....never any issues.....

My '18 does the same thing. I thought it might have something to do with the rear lid latch...It's annoying but no big deal, I guess.

I get the sound from the rear passenger side and happens occasionally. I kind of wrote it off as normal

Yeah, same here. Not a great bother though.

movement between the rear main & helper springs???

I had on a 991.2 GTS Vert ... it was really noticeable when getting on it in second and third gears, it almost sounded like I ran over a rock and it clanged under the rear of the car.

Had the car checked out and everything was where it was supposed to be so I just let it be ... it never resulted in any physical symptoms whilst driving, it was just off-putting to hear it. Its was intermittent though, I couldn't replicate it at will.

Not sure if it's the same thing but I thought I'd note it in case it is.

My Touring does the same thing. Sounds like it comes from the right rear. Glad to hear it's probably normal.
