Honda always recommend their ATF for their transmission, people quit using them because they believe it causes damage to their V6 trannies.
What I'm saying is, do your research and stop listening to car makers.
For porsche coolant, just get any coolant that does not contain silicate, nitrate, or phosphorous. Try Zerex for asian car that is pink color.

If you thoroughly and completely drain and flush out (multiple times) the system to remove any trace of the OEM coolant, you can use just about any aftermarket aluminum/alloy compatible coolant in these cars.
That said, if there is
any trace of the OEM product in the system, and you happen to choose an aftermarket brand that is not compatible with the OEM coolant, well, good luck cleaning out what happens next.
Then add in the fact that the OEM product is
very good both in protecting the alloy components and in how long it can live (properly installed, we have seen it go 7-8 years without problems and still test fine), it is readily available, and not all that expensive; and you have to ask yourself "Why bother looking for a substitute?"
