RR3 Wiki:Upgrades Strategy For 100% Completion

Introduction
This information is in transition from Aston Martin Update (v5.6.0) to Red Bull Ring Update (v6.0.0). See the last heading of this page for more information.

This is a guide to what upgrades to acquire, not when to acquire them. It's also worth noting that subsequent updates may lower PRs and make some of the current upgrades strategies redundant.

If you have any doubt before upgrading a car, save your progress to the cloud before spending. It's also a good idea to download the save just after you've uploaded it to verify the save succeeded. It is recommended to check whenever possible that the information is correct before spending, as a mistake may have gone unnoticed.

This page has been updated to include all series, even R$ only ones though some R$ upgrade costs are for full R$ upgrades and not the required R$ at the moment. It has also been changed to show the total reward for each series as this is much easier to maintain and will only record upgrade and reward costs once. If there is a duplicate strategy then the cost will only be shown against the first series. Only cars that can complete a series are included and the total BRL and that can be won is recorded as the reward against the optimum car.

All calculations are based on a new player starting Real Racing 3, there are too many computations to calculate the best strategy for all players, with different cars at different upgrade levels. If a series is started with car(s) at or below fully upgraded with BRL, then best strategy should be as stated, if any car(s) are already upgraded above upgraded with BRL, the player should check the alternative strategy. Most of the time, to complete a series to 100%, all cars will need to be purchased (with a few exceptions, such as NASCAR All-Star Series or Endurance Kings, for example).

Sometimes, different strategies (for the same cost) to the ones listed below may exist: when this is the case, R$ cost and performance improvements were taken in consideration to pick the most beneficial upgrade.

Total Cost
This table just gives a general idea, as it does not take into account cost for cars or cost to fully-upgrade with R$ all cars.

This only takes into account cost to upgrade acquired cars to meet PR requirements against full rewards for each series (even if they can be won without all the upgrades). Table still needs to be automated and validated against All Cars Base

The re-partition of costs is idealistic and assumes each category is completed one after the other.

Additionally, Time-Limited Series total a cost of   and R$?,???,???, with a reward of   and R$?,???,???, for a margin of  and -R$1,664,100, which does not include tier unlocks to 100% completion of the series. This isn't included in the table, as it doesn't contribute to 100% completion.
