Boxster 986 usable wheel sizes?

[Mikluuutus]

I'm buying winter wheels for Boxster S (year 2000) and would like to know more about what wheel sizes I can use. Manual says only these sizes:

17-inch:
front 7Jx17
rear 8.5Jx17
Offset 55mm, 48mm, 50mm

18-inch:
front 7.5Jx17
rear 9Jx17
offset 50mm, 52mm

Now I'm specially interested can I put 16-inch wheels like these:
front 6x16, offset 50mm
rear 7x16, offset 40mm
without any modifications (spacers etc.)?

or can I put these kind of 17-inch wheels?:
front 6.5x17, ET55
rear 8x17, ET40
without any modifications (spacers etc.)?

Does the car's behaviour change a lot if I choose to take either those 16-inch wheels or those 17-inch wheels specified there or do they even fit to the car straight away?

Thanks in advance!

16 inch wheels will not clear the rotors on an "S" model 986, you are limited to 17 or 18 inch.

Does anyone of you happen to know if 19" wheels fit Boxster S, year 2000?

front: 9x19 ET53
rear: 10x19 ET38

Ebay say it does but can I trust that? I know they fit to Boxster 2.7L from year 2000 but what about the S model?

Thanks!
