One hour straight to explain this a little bit more. As in the Upgrades section, there seems to be more than 1 tenth of precision in the calculating. Now I have more time, I am trying to solve this great problem. There seems to be 3 different ways to calculate it:

Method 1
The formula is the next:

top speed x grip / (acceleration) - braking
All in kph, s, m and g. Useful for cars with a grip of 1g or less. Example:

Lexus IS F (2013): 300 x 0.98 / 4.4 - 31.3= +-35 (Reality, 28.3)

A great approximation number, but not a really good one. Let's try with other car:

Chevrolet Cobalt SS: 257 x 0.89 / 5.69 - 35.9= +-4.3 (Reality, 3.7)

Yes, that is real. In fact, there should be a fifth element, the cornering (or handling). As that car has a little bit of bad cornering, it decreases 0.6, not so much. I don't know if I am right with this method.

Method 2
The formula is the next:

No more time left, continue in a few hours!!! You can contribute too, looking out for the importance of top speed, acceleration, braking and grip. See ya!
