There's 2 way to present upgrade.

"+/-" way

There is assumption that (1) earning R$ is easy compared to earning gold so (2) their biggest interest would be what is the minimal gold required to meet the PR.

That's the reason why this article use "+/-". At least it is guaranteed that they would upgrade the car as much as possible only spending R$ (This is the meaning of "Fully R$ upgraded"). It is promised that they would do at least R$ upgrade. So from one perspective It is rational to only present additional required upgrade because R$ upgrading is guaranteed.

Numbering way

The only reason to use this way is because It is hard to use "+/-" way. It is hard to type + and  - on mobile. Just typing 123456 is easier. Every time the event rleased, many people quickly try many ways to match PR. So they want to type many ways to upgrade. Nobody would type (Hellcat)  "The best way is +2 Drivetrain & Body & Suspension & Exhaust & Brakes & Tires and Wheels". I would definately type "The best way is 133333"

Personally I like numbering way.
