@AleisterDH Hi thanks you for your feedback, I working on it after 2 month. The car slide a lot because she is fast, and in real life this car have 600 horsepower and many torque too so when I did the handling I try to get same stats than real.
If it's a problem I can work on a handling who is more simple to drive. I work on handling I have many problem with, so the second and last update will be the last update of the car for the moment (Maybe other bugs/glitch will be found).
And for the windows normaly it will be fix ;D
