There are several threads on wheel fits for different year 986/987. I believe you'll have issues with the 10 wide rears on the 2000 S.
There are also more than one repro of the Carrera Light wheels, be careful. Better to spend too much than have a cheapo break and do serious damage to your car.
Try doing a search for "The Wheel Thread" tons of good info and many, many, many cool wheels.

Hope you have all night!!
