It's easy to find any part via part number:
https://www.porsche.com/all/media/pdf/originalparts/usa/986_USA_KATALOG.pdf
Front Strut PN: 996 511 551 01
Rear Strut PN: 986 512 551 01
So they aren't the same, fronts look to be about $15/each aftermarket, or $25/each for Stabilus which is the OEM supplier.
