Parts Realism + Quota

Oops, sorry, I was talking about 1 car leagues, where, effectively, you only need half of the parts that you gain per season.  A percentage of the other half can go and help other teams in lower divisions, in that case.
What might be needed, to make this work is for teams in 2 car leagues to gain parts per car equating to about the sane amount (of parts gain for each separate car) for a 1 car league.

Do not forget that this is meant to be a FUN GAME for all abilities.  I believe that your idea will turn this into a niche game for experts only...

Erm, i’m level 20 on the building, so i receive max parts but i use between 11 and 13 parts per car to repair per race. I’m in a 2 car league so i use double the amount of parts compared to you.

Going bankrupt on parts is a thing in 2 car leagues, believe me.

Let's recap:

Changes:

• 3 engine component changes a season (ICE, TC, MGU-H, ES and CE)


• [2-7] part component changes a season (suspension, brakes, gearbox, front wing and rear wing)


• 5% budget deduction for violations


• Slower part and engine wear, but the stats of cooling and reliability will impact it more


• Make cooling and reliability more important


• Parts to make a bigger impact on races

Motives:

• Make iGP Races better and more competitive


• More management requirements (since this is supposed to me a management game)


• Players should balance out the CD Requirements

You do not need to worry about that, the way parts are changed will only be a single click. Only the amount of repairs, the wear rate and the limit of changes will change (and that's a lot, but at least you can still repair parts in a click in the repair interface)

The part separation is for Elite. Pro will only have separate parts and Rookie will still have the current formula.

The others is for all series.

Er, no speed difference? Are you sure?

Parts play absolutely no role in this game

The 5% budget fine for violations wouldn't work. Teams with low or negative budget could repair as much as they want and wouldn't pay much. Also if there's a minimum fine it would it still means able to repair every if buying enough token to pay for it. Either a manager can't exceed the given repairs or the penalty has to be something that can't be bought for token, like a time or placement for Qualification or race.
