Beyond simply adding parts, tuning allows you to fine-tune your car's behavior. This is where you can truly tailor a car to your driving style and specific track conditions. The 'Tuning' menu offers a wealth of adjustable parameters:

- Tires: Adjust pressure for grip and temperature.
- Gearing: Modify individual gear ratios and final drive for acceleration or top speed.
- Alignment: Camber, toe, and caster affect tire contact patch and cornering.
- Anti-Roll Bars: Stiffer bars reduce body roll but can lead to oversteer/understeer.
- Springs: Adjust stiffness and ride height for handling and ground clearance.
- Damping: Rebound and bump stiffness control suspension movement.
- Aero: Adjust front and rear downforce (if applicable) for high-speed stability.
- Brake: Adjust balance and pressure for optimal stopping power.
- Differential: Adjust acceleration and deceleration lock for power delivery and traction.
Tuning can be complex, but even small adjustments can make a big difference. Start with small changes and test them. There are many community-shared tunes available, which can be a great starting point if you're new to tuning. Don't be afraid to experiment!
