Outdated RPX 2021A1 - Ultimate race car 1.2

1. change front and rear aero kit.
2. even STRONGER engine output but smoother.

3. reinforced chasis and axle for better extreme high downforce stability.
4. top speed down from 402km/h to 387km/h (airspeed).
5. increase downforce to 13072kg at 350km/h. max lateral G-force increase from 13G to 17G.
6. increase turning hydro system force.
7. decrease car weight to 528kg because i make it thinner.
8. there's a RWD transmission if you wanna try it without turbo. And i don't recommand you use that with turbo.

Note:
1. The tyre friction setting is all default from Automation exporter. But i increase tyre pressure and side wall stiffness to prevent tyre explode from stupidly high downforce . However, it also make tyre feel really grippy and very bonuce at low speed (below 120km/h).

2. It can do a burn out without care that much of axle explode now.
