Thanks to you all for all the feedback. @Preyupy, I will wait patiently for those numbers, really appreciated. If you are interested on simulation software I really recommend to check it out. I'm actually using rFactor and it works with applied physics formulas, so the behaviour of a car is really matched out. The best way to use it is with a good forcefeedback steering wheel hardware, the best quality/price is the Logitech G25. I've made some cars and some of them has been checked by real owners who give faith of the realistic them are. (I'm don't making this for money or marketing, really, this is a hobby which I enjoy a lot). I want to mention too that soon I will port the cars to rFactor 2, which have a really top noch tire and chassis flexing physics model, which give the simulation a really good approach of what is expected from reality. This is a pic attachment of the actual 2002 Turbo I'm working on. Hope you like it:
