UM Mercedes AMG F1 W12 E Performance

The Mercedes-AMG F1 W12 E Performance features one of the most sophisticated brake systems in sim racing, built around a dynamic brake bias migration system that adapts to aerodynamic load changes. The car employs a base brake bias setting that shifts forward progressively as pedal pressure increases, with migration values adjustable from 1-10 (adding 0-9% to the base bias). This system is essential for managing the dramatic downforce variation in modern F1 cars—at high speeds, massive aerodynamic loads allow aggressive front bias to maximize stopping power, while the bias automatically shifts rearward as speed decreases to prevent front lockup.

Setup strategy centers on finding the right base bias for corner entry stability, then using brake migration to optimize peak braking performance. The Begin Bias Ramping setting determines when migration starts during pedal travel, typically set between 30-50% to match your driving style. Higher base bias increases directional stability under braking but risks front lockup; lower values improve rotation but can trigger rear instability. The system also includes a Brake Magic mode for warming tires under safety car conditions, activating a preset front-heavy bias via steering wheel control.

The differential's Entry Preload and Entry settings work in concert with brake bias to shape turn-in behavior. Higher Entry diff settings add understeer during deceleration, requiring slightly lower brake bias to maintain balance, while softer Entry settings allow more aggressive rear bias without instability. Engine braking adjustment provides another tool for fine-tuning rotation on throttle lift, with lower EB values increasing off-throttle oversteer—useful for tightening the car mid-corner without touching the brake pedal.
