Mclaren 720S GT3

The McLaren 720S GT3 V2 features a sophisticated braking system with adjustable master cylinder sizes at both axles, three brake pad compound options, and a 12-position DSC system. The master cylinders allow precise line pressure tuning—larger cylinders reduce pressure and shift bias, while smaller cylinders increase pressure and pedal sensitivity. Brake pad compounds range from Low (maximum modulation, reduced bite) to High (aggressive bite, less modulation), with Medium serving as the standard GT3 baseline. The DSC system scales from minimal intervention (position 2) for dry conditions to maximum support (position 12) for wet weather, with position 1 disabling DSC entirely.

Brake bias is adjustable in-car and typically runs above 50% to the front, balancing stability in braking zones against the risk of front lockups. The bias must be coordinated with camber settings—adding negative front camber increases mid-corner grip but reduces longitudinal braking performance, necessitating a rearward bias shift to compensate. Weight transfer during braking is managed through damper tuning, particularly low-speed rebound damping which controls pitch rate and can increase braking stability when stiffened.

Aerodynamic setup directly impacts braking behavior. If rear ride height rises beyond target during braking (exceeding 70mm dynamic), the balance shifts forward while overall downforce drops, creating instability. This braking consideration governs how aggressively you can target maximum downforce setups. The differential preload also influences braking transitions—higher preload reduces lift-off oversteer and smooths the transition from brake to throttle in slow corners.
