Post yours tunes to share all yours (porsche platform) knowledges with everybody here in GTP, it´ll be a pleasure for me and everybody to test. Why not your own garage ???
For my RUF tunes, this is the way i like to drive them in the game. I don´t know how a porsche drive, i don´t and i will never have money to buy or test a real one.
Like i say, i´m just a fake tuners of fakes cars.
About your suggestion \\read a book, article, journal, or something about vehicle geometry and suspension physics in general// i think that to not know a lot about can help to tune in this game. You say that \\the game become more accurate in Suspension phyiscs// ???? I don´t think so. At least the ride height is backward and the springs value are not very accurate and you need some unconventional tricks to make a car work well in GT6.
Sorry for you if you waste your money with my garage.
