GPRO PHA Guide — Power, Handling & Acceleration

What is PHA?

PHA stands for Power, Handling, Acceleration — the three core attributes of your GPRO car. Each track requires specific PHA levels. If your car falls short, you lose time. If you exceed the requirement, you don't gain — it's wasted potential.

Which Parts Affect Each Attribute

Power

Main parts: Engine (5.8), Gearbox (3.2), Electronics (1.4), Cooling (1.2). The engine is by far the most important part for power.

Handling

Main parts: Front Wing (2.45), Rear Wing (2.45), Brakes (2.0), Chassis (1.8), Suspension (1.6), Underbody (1.2). Wings dominate handling.

Acceleration

Main parts: Gearbox (4.1), Engine (2.1), Chassis (1.4), Electronics (1.4), Wings (1.2 each), Suspension (1.2). The gearbox is key for acceleration.

How to Balance PHA

• Check the track requirements in the HOME tab
• If your car exceeds all 3 attributes → don't waste money upgrading
• If one attribute is below the track → upgrade the parts that affect it most
• When parts wear out and need replacing → choose levels that balance PHA for upcoming tracks
