I think this is getting away from the original problem. I'm prepared to accept that you could probably get wheels suitable for a late offset Porsche to fit any other car (within reason) with adapers and/or spacers, but if you want to fit wheels designed for something with a smaller offset or PCD I think you'll struggle, because the offset & PCD on a late offset Porsche are already about as big as they come.
GTA - I think your best option would be to either find some aftermarket wheels you like that are designed to be used on a Porsche or find some used genuine Porsche wheels from a later model. Pretty well anything for a 968, Boxter/Cayman, 928 or 911 (964 or newer) will work, although some offset & width combinations may rub or look odd.
Bear in mind too that tyres supplied with a package like the one you gave a link to may not be optimum for your car either, the e-bay link is for 8" rims with 225's all round - fine for the front but narrower than standard for the rear. It you just want some bling for cruising fair enough, but if you like to use the performance of your car it's not an area I'd skimp on.
As far as performance goes the standard 16's or some 17's would be up to the job.
