Here is a masterpiece of modding! Badass cockpit and a a real joy to drive. As possible improvement, I think the cockpit glass might give more reflection but I don't know if it's inherent with the Kunos' engine.
I found how to set the ackerman effect in the tab * suspension.ini *
On this line of code (example) "WBCAR_STEER = 0.99999, -0.0749, 0.07591"
The first digit after the symbol (=) (so 0.99999) to (,) coresponde has ackerman effect i did not try further.
By adding the symbol (-) you get the anti ackerman effect
