Weight vs Power Upgrades — How to decide between shedding kilos and adding horsepower

Understanding weight vs power upgrades is what separates casual players from consistent podium finishers in FH6. Most people slap on the part with the biggest stat increase and call it a day. Works fine against AI. Does not work online where everyone else did their homework. Here's what I've learned about how to decide between shedding kilos and adding horsepower after way too many hours testing.

The Decision Framework

Before you spend a single credit, answer three questions: What class am I building for? What kind of tracks? What's my driving style? A drag build wants completely different parts than a circuit build. A technical track rewards handling. A highway sprint rewards power.

Bottom line: buy the RIGHT parts, not the most expensive parts. A car 10 PI under the limit built with a plan gaps the maxed-out car with no strategy. Every single time.
