Or years of rFactor torture made me grow an extra sense, but I'd agree when you say thats unlikely. Still, I never really aim for a type of handling, I just improve the numbers as I find more data, so the outcome, apart from springs/dampers/rollbars etc is pretty much fixed. I'm surprised that this means such a light and powerfull car is stable, much like the underpowerd porsche 906 that didn't feel much like a light and nimble car. Always enough time to judge and react.
Perhaps the drivability of a car doesn't suffer too much from low weight and power, I recall Todd saying he spoke to a driver who said it was quite easy to go nuts in a overpowered caterham.
Anyways, wings could loose more downforce at yaw, currently simply diminishes from 100% to 0% as yaw reaches 90 degrees. Pitch and yaw inertias are some ~700kgm^2, which seems reasonable, centre of gravity sits 33cm above the road, which is a guess as always. Torque curves might be more peaky, we're in touchy areas where a few small changes can probably make a considerable difference. Perhaps its unrealistic to use 4 way adjustable dampers considering the era..
Then again the fun, not to mention amazement of chucking a 600kg / 450hp car around naturally playing with over and understeer, provoking turnin with a rearward brake bias, those are not things I (and many of you) would even dream about when it considers rFactor.
