Been noticing I get a low pitch groan at low speed turns every now and then. Mostly pulling into parking spots. It sounds kind of like when you run a wet finger around the edge of a wine glass. Any ideas?

Front tire rub?

RVAE34

Definitely not tire rub. I'd almost guess steering rack but fluid is normal and no signs of issues underneath.

At full lock by any chance? I recall having experienced that (or similar) at full lock occasionally...Haven't, knock on wood, in a long while.. then again, I barely drive this thing. I absolutely try not to go full lock.

The upper trim arrived at my local dealer. Was in two 10 foot boxes. So now the PN's are all confirmed.

Does it seem to be coming from the front of the car?

I had something similar and noticed the sound when I got out of the car as well, turned out to be a control arm that needed to be replaced.

RVAE34

It's definitely from the front. I've heard someone mention a noise associated with control arm failure but I'd never expect it to be that kind of noise. I'll see if I can do some more research.

summer tires in the colder weather?

Any chance you can get a video with the sound?

It's pretty unmistakable to hear.

RVAE34

I can try but doesn't happen often and really only when parking so hard to record.

Trying to post the video I took but not having luck.

Funny, that turning groan noise just started with mine. Only hard to the right.

Had the wife turn the wheel while I had my head under the hood. Couldn't hear the noise there so might be in the steering system underneath? I know there was a recall but mine was already serviced.

RVAE34

I'd say it's in the steering system with 90% certainty.

Got my 14-16 rear diffuser pieces but they sent me chrome trim instead so those pn's were incorrect..

The correct night trim pn's for the rear diffuser are

212-885-10-00
212-885-53-21
212-885-54-21

The OEM CF diffuser is too expensive. Just the tow hook cover is around $200. I'll keep searching for a renntech diffuser for sale.

this sound happens to me fairly consistently, kind of like a groaning on very low speed turns. I'm on H&R fronts. my mechanic told me it was because of the lowering, now that the suspension (I forgot the specific name of the part he referenced) is sitting at more of an angle than at OE height. he said there is nothing he can really do to alleviate the sound.

I hear it most often when the car is parked overnight and I take it out in the morning, the suspension is stiff/cold and it produces the sound.

gorgeous spec 63, btw.

You know, that makes a good bit of sense. Since it's a macpherson strut, It might be binding on slow turns. I will try greasing the upper hat and spring to seat.

The groaning noise is pretty common on these cars. Mine seems to do it in the cold more so than in the summer.

Very nice...are those CLS wheels, sizes ?

RVAE34

Thank you! Factory painted white wheels and badges. Designo Performance Studio custom order.

Got it, I thought you had bought another set

I had a similar set on my 997 TT and kept the wheels when i sold the car. I still have the wheels, very rare factory option

Why did you sell such a beautiful machine?

I REALLY want a 911 next.

RVAE34

No regerts lol.

I can't believe I almost sold my car before the market went nuts. It would take more than 6 figures for me to let it go now.

That is a gorgeous 911 btw!

Beautiful Wagon.
I did have a couple of questions,
Did you replace the stock struts with aftermarket?
if so, were you able to to retain the adjustable suspension?
C-comfort, S-sport, S+ - Sport Plus?
