Audi R8 LMS EVO II GT3

The Audi R8 LMS EVO II GT3 offers comprehensive brake tuning through adjustable master cylinder sizes, three brake pad compounds (Low, Medium, High), and in-car brake bias adjustment. The dual master cylinder system creates an inherent bias based on size differential—larger front cylinders reduce front line pressure and shift bias rearward, while the inverse moves it forward. This mechanical bias interacts with your electronic brake bias setting (displayed as percentage to front brakes), meaning different cylinder combinations require different bias values to achieve the same balance.

Brake bias tuning is intimately connected to aerodynamic platform stability. During heavy braking, rear ride height increases as weight transfers forward—if this exceeds your target dynamic height, you'll experience both a forward aero balance shift and total downforce loss, creating instability exactly when you need confidence. This relationship means your optimal brake bias must account for chassis pitch behavior, not just front-to-rear grip distribution.

The ABS system offers 12 positions: 1–6 for dry slicks, 7–11 for wet conditions and 12 to disable the system. Within the active ranges, higher settings provide more intervention. Low brake pads provide less friction and more modulation; Medium and High increase friction while reducing modulation.
