GT4RS clicks when turning

GT4RS clicks when turning
Hi guys, I need your help and advice!
While driving at any speed, when I turn right from 30 to 100% steering wheel I hear a clicking sound from the front left wheel.
1. When the car is hotter, the clicking noise is heard more strongly.
2. There is no noise when driving straight or backwards.
3. The front left wheel only clicks when turning right.
4. The right front wheel is silent.
5. Depending the faster the speed, the more repeated clicks noise.
6. CL was tightened (600 Nm) several times and Molub-Alloy paste was changed.
7. Wheels swapped left with right.
8. Checked all the elements under the arch, nothing is healing.
9. The mating surface of the wheel and brake disc was cleaned
10. No stones in rotor e.t.c
My car:
Full stock
EU GT4RS
10/2023 prod
PCCB
WP
OEM Alloy wheels
1500 km
Anyone have the same problem?

check inner wheel weights aren't touching anything. not 4RS but GT4 and this was my problem too. moved wheel weight and the air deflector it touched.

This may not be the same issue, but my friend put 255 width tires on the front of his RS, and he noticed a clicking sound coming from his front passenger wheel well when turning. The sound got progressively worse, and could be heard even at slow speeds (around a parking lot).
We found the tire was rubbing up against some of the ducting in the front wheel well, and broke the duct and lining around it—causing the broken plastic to cause a clicking sound when hitting the tire. We found it because it was pretty easy to see from the outside when the car was turning in the parking lot, and the trim and ducting was coming in contact with the tire.

Tomorrow there will be a lot of work in the service.

1. Removed both front wheels, left and right, cleaned the mounting
surfaces and degreased.
2. The brake calipers were removed and checked for defects and damage.
3. The PCCB brake discs were removed, the hub part was cleaned and degreased, no damage was found.
4. The hubs were removed and cleaned of corrosion and degreased.
5. The pins were removed from the hubs, cleaned and degreased.
6. The wheel bearings were removed, cleaned and degreased; there was rust near the drainage hole.
7. Cleaned the springs from debris and stones
8. Checked BILSHTEIN support bearings
9. Swap the support cups from left to right (they are interchangeable, same part number)
10. Shock absorber rods checked
11. All plastic air ducts, brake cooling (NACA, etc.) have been checked.
12. The wheels do not touch anything, the loads do not touch the caliper, and the air ducts do not touch.
13. Stabilizer link and stabilizer checked
Surfaces were cleaned: Scotch-Brite pad 7448
Paste for Cl used Castrol Molub-Alloy Paste TA
I attach all the photos that I managed to take during the work process. Don't judge strictly by the quality of the photos))
I spent the whole day. Tomorrow I will test the car, I left it at the service center. It's already night outside.

bad news or good?
All manipulations with the front part of the car did not produce results.. after that, i went home upset, I read a ton of topics on other Porsche models here.
Many other cars with CL had the same problems...
50% solved them in different ways,
50% say that this noise is just the norm...
I don’t even know what to do, but I don’t want to give up. I found a service where we connect 4 microphones to different parts and look for the noisiest one and only then change or repair something.

I'm assuming all this work was done at the dealership?
I'd not take it back until they have resolved the issue. File a case with Porsche HQ. Sorry about this!

I think it's the brake duct hitting wheel weights.
When suspension is loaded the duct will be closer to the inner edge of the wheel

1) Does it also make the sound when Nose lift is active? (This could eliminate the brake duct rubbing anything)
2) When you have someone outside the car (when filming) would it be possible to listen carefully where the sound seems to come from?
3) Could you mark one wheel spoke, and the north position on the fender (detailers tape) and film a full rotation of the wheel while it makes the sound. Film in slomo. When you know the amount of clicks per 360 degrees, you probably can spot the one item that has this amount of tooth, spokes, nuts, etc that is rubbing
