It is feuerdog , anglo'd from the original "feuerhund" (translation: fire dog), not Feverdog.
No one has posted a Porsche calc based on v5.11a.
Go ahead, correct me, please!
This calc link below (based on v3) has a Porsche tweak, but I do not know if it has been updated to v5.11a. I doubt it.

v5.11a has a RR tweak (Porsche are only cars with this configuration), but it is far from close to a smooth ride.
Enter your inputs, then tweak till you get a ride that works for you.
I did, and am OK with my final settings, for my RR Porsche cars, my MS wheel, and my driving style...
That's what these calcs are all about, get close, then fine tune.
