UM Audi R8 LMS GT3

The Audi R8 LMS GT3 features a sophisticated brake system built around adjustable master cylinders and three pad compounds. Seven master cylinder sizes are available for both front and rear axles, ranging from 15.9mm to 23.8mm, allowing precise control over line pressure and brake bias characteristics. This flexibility means your in-car brake bias adjustment range will shift depending on your master cylinder configuration—smaller front cylinders increase baseline front bias, while larger rear cylinders do the same.

The car's ABS system offers twelve positions with ten distinct maps, with position 4 recommended as your baseline. Higher ABS settings provide more intervention and stability but can extend braking distances if set too aggressively for available grip. You'll want to experiment with ABS levels as track conditions evolve, particularly as tire temperatures build or grip deteriorates.

Braking performance is intimately connected to your suspension setup, especially camber. Increasing front negative camber improves mid-corner grip but reduces longitudinal braking force, requiring a rearward brake bias shift to compensate. Similarly, compression damping adjustments affect weight transfer speed during braking—higher compression damping accelerates weight shift forward, potentially improving initial bite but reducing overall front grip. Monitor tire temperatures across the tread to ensure your alignment choices aren't compromising braking performance.
