Don't take it quite that steeply, I don't hate you but the sad truth is that there is no formula to fit all cars excellently. What I'm trying to say is that your formula will always be worse than a customized setting for a certain car. You're only making yourself look dumber than you are by stating that it will work fine on every FR, MR and 4WD car. It won't, I know from experience that there are cars that need very odd tuning to behave acceptably. A certain formula is a good starting point but every car will need its own fine tuning.
I tried it out. Not on those very same cars, but I usually don't base critics on an "I think" basis as it would look (and be) extremely silly. The main problem is that the weight transfer is completely ignored by the very hard suspension, and the result is that the tyres get overloaded which leads to losing grip. Softer and higher cars are more responsive until a certain limit, after that limit the effects will begin to reverse. Camber is always needed outside of the drag strip as it greatly increases cornering grip. And the fact that you used ASM proves that there is something wrong with the formula.
The cars you've used, with the exception of the Impreza, are very wide, low and stable cars that usually have a hard suspension with a low ride height. The results about the overall suitability would have been really different if you had tried out, for example, Shelby Cobra for FR, Lotus Europa for MR and Audi TT for AWD. Those are all cars that need pretty specific tricks to make them drive well and even if you say that the formula will work fine, the cars will be close to uncontrollable with it. Always take into consideration all the different possibilities when making "universal solutions". I've done those before myself and found out that they don't work 100% of the time.
What I'm trying to tell you is that every car is different. Believe me or not, I'm trying to help you, even if my way of doing it is a bit weird. I'm not saying that it's the worst tuning I've ever seen. You should see what I've seen in this game series. And you don't want to know all that.
And don't apologize for your English, as long as you're doing your best writing it it really doesn't matter if you don't get it right. Txt spk is the way to get flamed, not having English as a native language is definitely not.
