Not to be a smart azz, but sure, you can do anything you want. But figure Porsche specifically spent the time, money and other resources to redesign the system when through accidents, failures, stress tests, engineering studies, etc, they (Porsche) determined the design was inadequate to safely support an 18" wheel. So they redesigned the system. And this was after only one year worth of results on a new car. Your car is now 24 years old.
Can you get away with it? Maybe. But maybe not. Remember - your car is now 24 years old and has gone through numerous, numerous stress cycles. The rear suspension certainly isn't stronger now than it was 24 years ago when the car was new, so that fact alone should make you stop and give thought. You're wanting to add more weight, more rolling mass (both of which will wear the suspension faster) and more expensive tires.
The guys that have responded here to a person say "no", and they are all probably smarter than me about these cars. You asked a question and the collective knowledge of the group gave you an answer. What you do with it is up to you.
Why are you so hard over on 18" wheels? Just asking. There are a ton of good looking 17" wheels around.
