F1 2020 Performance mod for 2021 1.9 FINAL

Following the concept and edited lines from the improved dirty air mod by StrongestFish, I decided to keep dirty air the way it is (0.85 of your downforce when following) but decreased drag on the straights from 0.9 to 0.85 to slightly improve slipstreaming effect. If this mod is successful I can add more versions of it with different dirty air and slipstreaming or damage conditions.
Edited lines are: airdensityscalelift and airdensityscaledrag by searching them in the notepad.

Disclaimer: the mod does not change UI and graphics or performance charts in-game. "My team" vtf files and performance were only modified to reflect the damage mod and the modified slipstreaming, the engine and performance of myteam cars are intended as in the original game. As Williams and Alfa Romeo are slightly improved in this mod and Haas decreased, it's likely that the beginning of your "my team" car will be more difficult compared to the standard game.

As per my discussion in the forum - https://www.racedepartment.com/thre...al-error-and-discussion.201879/#post-3378968- I decided to focus on rebalancing overall performance. My workaround consists in swapping lines for every sector/departments from a car to the other.

For doing so, I used the 2 engine tiers and performance files from the pre and post performance patch that came out in October 2020. My reference about values was this video from Alex Gillon that analyzed the modifications after the October performance patch.

The values I considered are therefore engine, downforce (the higher, the better), then drag and chassis mass (the higher the worse).
In the original game Red Bull has an engine value of 581,6, downforce 2.100, 740 chassis and 1.047 drag; Mercedes has the same aero, a little bit more drag at 1.050 but superior engine at 596.5.
How my overall is calculated: I add engine to downforce with no decimals, then subtract mass and subtract drag with no decimals.
So if Red Bull has 581.6 + 2100 - 740 - 1047 it gest an overall of 894,50 (almost 9 out of 10). Mercredes has 596.5 + 2100 - 740 - 1050 = 906.50.

1) How to make Red Bull just a bit stronger and keep Mercedes as a benchmark?
As per RedBull and AlphaTauri improvements I made Honda become a top tier engine. As per Alex Gillon's video, before the peformance patch there were 2 high tier engines (Ferrari and Mercedes with overall value 596.5) and 2 lower tier engines (Honda and Renault with value 581.6). So I gave to Red Bull and Alphatauri the same lines of the Mercedes engine - Including gearbox and fuel tank to make Honda engine top tier. To do so, I did copypaste the whole first part of the VTF file until the end of the fuel tank section. Fuel section is very important as only the higher tier engine feature the more powerful "fuel max" mode with a multiplier of 1.08 instead of the 1.07 of the lower tier engine.

2) How to improve Ferrari and McLaren?
As Ferrari's power unit and drag conditions improved in 2021 compared to last year, and as in my opinion the performance patch was too forgiving to the real engine and Ferrari performance, I decided that the lower tier engine did not need improvements or downgrades. I gave back Ferrari the stronger performance base they had before the October patch, so Ferrari now has 740 mass, 2.067 downforce (improved) and 1.060 drag instead of the current in-game 2.026 aero (still a good aero, in par with McLaren) and 1.092 drag (awful amount of drag, even more than Haas). But I did respect the fact that Ferrari has a lower tier engine now so I just switched the engine lines from the new Ferrari to the old one bringing it from 596.5 to 581.6. Upgrades was changed accordingly. So Ferrari should be performing well in technical circuits due to a good aero but will suffer on the straights against Mercedes and Honda engines.

McLaren had already a strong base with mass 746, drag 1.029 and downforce 2.026 so I just gave them Mercedes engine and made their mass 740 to put it on par with Ferrari, Mercedes and Red Bull. So McLaren will be stronger on the straights and in power-hungry circuits but Ferrari has a little bit more aero to balance other kinds of circuits where more downforce is required Overall McLaren should come out on top more than Ferrari, on paper.

3) Racing Point / Aston Martin get back near to the level they had before the patch, thus having a mass of 744 instead of 742, drag 1.052 instead of 1.060, aero 1.984 instead of 2.037. Engine remains Mercedes engine, nothing changed here. This aims to reflect the troubles Aston Martin had since the regulation changes which put them not in condition to fight for the 3rd place anymore.

6) In the low field, Alfa Romeo gets back its pre-patch performance + improved but keeps the Ferrari engine, has a mass of 746 instead of 750 and gets tweaks to aero and drag. Williams gets also improved a bit. Haas gets Williams in-game performance but with Ferrari engine, to reflect the fact they are the last force this year. This should put Williams only a little bit behind a very solid Alfa Romeo ready to score points given the right conditions.
