Help Identifying AMG Wheels

[911F]

Can anyone help identify these 18" AMG wheels from a facelift SL55 (2006+)

I'd like to know the part numbers.

thanks

Wow! That's impressive! Thank you..

Next question: Best place to get a new set (not paying dealer pricing)

Thats brilliant - thank you.

The only Problem I have is that it seems Mercedes have changed the Part number on these wheels, they are now:

B66031119 and B66031120

Does that mean the finish is different?

Thanks
