Suggestion
Potentially you could fit 20" rims by adjusting the tyre profile to compensate.

Suggestion
I looked at changing my 4S rears to 325 from 305 but in order to not mess the AWD up I would have also had to change the fronts from 235 to 245 .

Suggestion
Apart from not knowing what a 994 4S is :dont know: :?: and assume its a typo and you meant 996, but as long as the offset is the same you should be ok re the alloy but with the AWD if you change the tyre width at the rear you need to change the front as well or is may mess up the AWD system, so are you going to fit the same size tyres to the 10" as the 11" in which case your ok but if not then consider what your going to do with the fronts .

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

With the 4WD system, as long as you keep the rolling radius near front & rear OEM spec then all should be fine. Potentially you could fit 20" rims by adjusting the tyre profile to compensate. Sure it would probably be running a 20 or 25 series profile tyre and the ride would rattle your fillings but it is achievable.
Plenty of tyre profile calculators on the web if you have a look.

If you fit a narrower wheel of the standard offset with a spacer, you'll move the centre of the tyre contact patch out. That may have implications for handling. It might fit, but it might not work very well, especially if the tyre is narrower as well.
Thanks for the response guys nd yes did mean to type 996.
I will be keepig OEM Porsche tyre spec but if i do go wider i would replce front and back to keep the same.
