Once you've upgraded your car, tuning allows you to fine-tune its behavior to your driving style and specific track conditions. This is where you can truly unlock a car's potential.

Key Tuning Parameters:
- Tires: Adjust pressure for optimal grip and temperature.
- Gearing: Customize individual gear ratios and final drive for acceleration or top speed.
- Alignment:
- Camber: Angle of the wheels. Negative camber improves cornering grip.
- Toe: Angle of the wheels relative to the car's centerline. Affects turn-in and stability.
- Caster: Angle of the steering axis. Affects steering feel and stability.
- Anti-Roll Bars: Adjust stiffness to control body roll and balance oversteer/understeer.
- Springs: Adjust stiffness to control ride height and weight transfer.
- Damping:
- Rebound Stiffness: How quickly the suspension extends.
- Bump Stiffness: How quickly the suspension compresses.
- Aero: Adjust front and rear downforce (if applicable) for high-speed grip or straight-line speed.
- Brake: Adjust balance (front/rear) and pressure for optimal braking performance.
- Differential: Adjust acceleration and deceleration lock for power delivery and stability.
Tuning is an iterative process. Make small adjustments, test them in Free Play, and observe the changes. There are many community-shared tunes available, which can be a great starting point if you're new to tuning. Experimentation is key to finding the perfect setup for each car and track.
