I think I did it this time, if you didn't see the last post, #here it is

Today I spent the whole day, I achieved a result that satisfies me. I could add more details, but I want to save on details and have a stable 60 fps.

In fact, during the day I managed not only to change the rear side, I added an active wing, a spoiler. I worked hard to make his work correct so that it was adjusted to each driving mode.
Oh yes, I also added 3 driving modes (road,track,drag). right now they only interact with the rear spoiler.

I plan for the stiffness, suspension height, stiffness of the stabilizer bars and aerodynamic elements in the front to also change during driving.Therefore, I still have a lot of work to do and the release will not be soon, but for now you can admire the screenshots
