Ok *REVISION* I initially gave this tune a 5 stars, which I'm keeping for reasons that I know Ghostrider has done by far the most tunes for the community and has by far the most flawless reputation..
Ghost I think you may have this one set up to be a little bit too safe. With the tune exactly as you have it listed, all assists/driver aids turned completely off, I decided to do some laps on Brands Hatch 1980's Grand Prix race track. This is a technical track that forces flaws to the surface very quickly upon pushing any vehicle. I use a Logitech Driving Force GT racing wheel (force feedback) and pedals. I have the steering set to simulation mode and am experienced at racing in GT6 as well as GT5 using this wheel. As a driver I will say that I'm very advanced and have aspirations in professional racing. I'm usually able to coax out a little bit of rotation from AWD race cars, through means of a somewhat aggressive driving style, with slightly more sudden and abrupt inputs with less motion progression if needed.(though these movements are precise and acccurate as well which took me a while to develop - one can be smooth AND fast just takes a lot of establishing muscle memory and practice)
Anyway, thw Skyline R32 GTR is one of those cars that has excellent adjustability in its stock form as well as after companies release their own custom modified versions. Due to that being an important defining characteristic I don't think this touring car should be so safe feeling, that in my opinion is the wheelhouse of the more luxury oriented Audi models, or for other race cars: AWD race cars with a very short wheel base and a wider track, after a certain wheelbase to width index I believe that AWD needs to be made more lively.
So I give it an unofficial 4.5 stars for now thanks
