Hello!
First of all: This is a sort of "rework" of someone else's mod. I have permission from everyone involved.
Second of all: It still is a mesh slap basing on the Scintilla and uses Scintilla Frame parts. Changing this and the whole model was not the scope of my rework.
Lastly:My goal was to make it handle like a Chiron and have performance similar to a Chiron, which it now has.

Make sure to use the most recent game version. BECAUSE THE MOD DOES NOT WORK IN VERSIONS BEFORE 0.28

Current Version: 1.35
-----------------------------------------------------------
-The engine performance and weight is accurate to irl statistics and turning Gs, acceleration and top speed is quite close to irl. Braking performance also is not far off.
The active aero wing works as it should irl and changes with the drivemode.

-The suspension height and stiffness also changes with the drivemodes! I used theofficial stat sheet of the Chironand some Trigonometry to accurately calculate the ride height change in game.

-The Airbrake has accurate braking performance and the brakes have my brake glow effect on them! The Airbrake makes 900kg of downforce at top speed, as it should, and braking from 400 takes about 9 seconds, as it should as well.

-Other things about the drivemodes:
The car will automatically change from EB into Autobahn mode once you crossed 180km/h
Only the Top Speed drivemode allows you to go faster than 380km/h!!
The car will automatically switch from Lift mode into EB mode if you go faster than 50km/h
The car will automatically switch from Lift mode into Autobahn mode of you activate lift mode when going faster than 180km/h

There are also some other small details! Such as the headlight shutdown and startup sequence.
