I did this recently, and wanted to post up the before/after pics.
Originally my car came with the 5mm spacers, but IMO they were useless - 5mm, thats less than thickness of a q-tip end - yup, useless.
One thing to keep in mind, is that I already did rear spacers install last week. So all pics have rear spacers in them (sorry, no comparison pics), however you can see the after result and compare the fronts to give you idea of how far the wheels get moved out with spacers in place.


The install was with the 20 inch Turbo 2 wheels, sizes:
- 255-40-R20 front
- 295-35-R20 rear



To do the job:

- Purchased 15mm spacers, one for each corner, total 4.
- Purchased 44mm wheel lug bolts (black) with R14 swivel washer - 5 per wheel, total 20 bolts.
- Brake cleaner for cleaning brakes while I was at it


I must say the 15mm spacers appear to be optimal for spacers on stock wheels for the Panamera.
If I installed thicker spacers, I think when the car lowers down, it would come extremely close, if not touch, the inner wheel well of the car.
So if you contemplate installing spacers, it is something to think about.

Here are some pics...before and after...

 

looks good

 

It made a difference for sure, like you said 15mm seems to be the right amount for those wheels, nice job!!

 

I too installed 15mm spacers on all 4 corners of my Panamera Turbo with the Turbo II wheels and the difference is striking. They really fill up the wheel wells now and make it appear like it has a significantly wider stance. I was really surprised by what a huge difference this made!

 

And does not make your 200k car look raunchy, like some Pontiac with 45mm spacers on, half tire sticking out.
I found that the 15mm is optimal at least for me. This way, if you lower and raise your Panamera, it will not affect how wheel fits in the well. Fills the well nicely and aesthetically.
Great to hear good results.

 

 

I got them off ebay. Hub centric wheel spacers 15mm.
Due to all of them being turned out or cncd, you should be good to go with them.
Make sure you get longer bolts, I think I put details in the thread, for type and length.

 

 

I just went without locks. When you get them the bolts should be longer than your OEM bolts by at least the width of the spacer.

 

 

 

It will certainly throw more slinging along the sides.

 

Yes, but you can now match everything up before installing them to be 100% sure and have peace of mind.

 

 

Ciaka,

Please send out the link where you bought the spacers set from. Thank you for the link to door lights at ebay. I just received them this afternoon. Will do a quick installation tomorrow morning before going to the office. LOL ...

Thank you.
